Golkonda Fort-Hydrabad

Golkonda Fort Front View
           
 Golkonda, also known as Golconda, Gol konda ("Round shaped hill"), or Golla konda ("Shepherd's hill"), is a citadel and fort in Southern India and was the capital of the medieval sultanate of the Qutb Shahi dynasty (c.1518–1687), is situated 11 kilometres (6.8 mi) west of Hyderabad. It is also a tehsil of Hyderabad district, Telangana, India. The region is known for the mines that have produced some of the world's most famous gems, including the Koh-i-Noor, the Hope Diamond and the Nassak Diamond.
 
Inside View of Golkonda Fort
          
Golkonda was originally known as Mankal.Golkonda Fort was first built by the Kakatiya dynasty as part of their western defenses along the lines of the Kondapalli Fort. The city and the fortress were built on a granite hill that is 120 meters (480 ft) high, surrounded by massive battlements. The fort was rebuilt and strengthened by Rani Rudrama Devi and her successor Prataparudra. Later, the fort came under the control of the Musunuri Nayaks, who defeated the Tughlaqi army occupying Warangal.[4] It was ceded by the Musunuri Kapaya Nayak to the Bahmani Sultanate as part of a treaty in 1364
.
            Under the Bahmani Sultanate, Golkonda slowly rose to prominence. Sultan Quli Qutb-ul-Mulk (r. 1487–1543), sent as a governor of Telangana, established it as the seat of his government around 1501. Bahmani rule gradually weakened during this period, and Sultan Quli formally became independent in 1538, establishing the Qutb Shahi dynasty based in Golkonda.[7][8] Over a period of 62 years, the mud fort was expanded by the first three Qutb Shahi sultans into the present structure, a massive fortification of granite extending around 5 km in circumference. It remained the capital of the Qutb Shahi dynasty until 1590 when the capital was shifted to Hyderabad. The Qutb Shahis expanded the fort, whose 7 kilometres (4.3 mi) outer wall enclosed the city.
            The fort finally fell into ruin in 1687, after a year long siege leading to its fall at the hands of the Mughal emperor Aurangzeb.
Diamonds
The Golkonda Fort used to have a vault where once the famous Koh-i-Noor and Hope diamonds were stored along with other diamonds.[10]
            Golkonda is renowned for the diamonds found on the south-east at Kollur Mine near Kollur, Guntur district, Paritala and Atkur in Krishna district and cut in the city during the Kakatiya reign. At that time, India had the only known diamond mines in the world. Golkonda's mines yielded many diamonds. Golkonda was the market city of the diamond trade, and gems sold there came from a number of mines. The fortress-city within the walls was famous for diamond trade. However, Europeans believed that diamonds were found only in the fabled Golkonda mines. Magnificent diamonds were taken from the mines in the region surrounding Golkonda, including the Daria-i-Noor or "Sea of Light", at 185 carats (37.0 g), the largest and finest diamond of the crown jewels of Iran.
            Its name has taken a generic meaning and has come to be associated with great wealth. Gemologists use this classification to denote a diamond with a complete (or almost-complete) lack of nitrogen; "Golconda" material is also referred to as "2A".
            Many famed diamonds are believed to have been excavated from the mines of Golkonda, such as:
Kohinoor Heera 

Daria-i-Noor
Noor-ul-Ain
Koh-i-Noor
Hope Diamond
Princie Diamond
Regent Diamond
Wittelsbach-Graff Diamond
By the 1880s, "Golkonda" was being used generically by English speakers to refer to any particularly rich mine, and later to any source of great wealth.
            During the Renaissance and the early modern eras, the name "Golkonda" acquired a legendary aura and became synonymous for vast wealth. The mines brought riches to the Qutb Shahis of Hyderabad State, who ruled Golkonda up to 1687, then to the Nizam of Hyderabad, who ruled after the independence from the Mughal Empire in 1724 until 1948, when the Indian integration of Hyderabad occurred
The Fort
            The Golkonda fort is listed as an archaeological treasure on the official "List of Monuments" prepared by the Archaeological Survey of India under The Ancient Monuments and Archaeological Sites and Remains Act.[11] Golkonda actually consists of four distinct forts with a 10 km long outer wall with 87 semicircular bastions (some still mounted with cannons), eight gateways, and four drawbridges, with a number of royal apartments and halls, temples, mosques, magazines, stables, etc. inside. The lowest of these is the outermost enclosure into which we enter by the "Fateh Darwaza" (Victory gate, so called after Aurangzeb’s triumphant army marched in through this gate) studded with giant iron spikes (to prevent elephants from battering them down) near the south-eastern corner. At Fateh Darwaza can be experienced a fantastic acoustic effect, characteristic of the engineering marvels at Golkonda. A hand clap at a certain point below the dome at the entrance reverberates and can be heard clearly at the 'Bala Hisar' pavilion, the highest point almost a kilometer away. This worked as a warning note to the royals in case of an attack.
            The whole of the Golkonda Fort complex and its surrounding spreads across 11 km of total area, and discovering its every nook is an arduous task. A visit to the fort reveals the architectural beauty in many of the pavilions, gates, entrances and domes. Divided into four district forts, the architectural valour still gleams in each of the apartments, halls, temples, mosques, and even stables. The graceful gardens of the fort may have lost their fragrance, for which they were known 400 years ago, yet a walk in these former gardens should be in your schedule when exploring the past glories of Golkonda Fort.
Bala Hissar Gate: is the main entrance to the fort located on the eastern side. It has a pointed arch bordered by rows of scroll work. The spandrels have yalis and decorated roundels. The area above the door has peacocks with ornate tails flanking an ornamental arched niche. The granite block lintel below has sculpted yalis flanking a disc. The design of peacocks and lions is a blend of Hindu – Muslim architecture.

Toli Masjid:-

            situated at Karwan, about 2 km from the Golkonda fort, was built in 1671 by Mir Musa Khan Mahaldar, royal architect of Abdullah Qutb Shah. The facade consists of five arches, each with lotus medallions in the spandrels. The central arch is slightly wider and more ornate. The mosque inside is divided into two halls, a transverse outer hall and an inner hall entered through triple arches.
            Much thought went into building this gate. A few feet in front of the gate is a large wall. This prevented elephants and soldiers (during enemy attacks) from having a proper ramp to run and break the gate.
The fort of Golkonda is known for its magical acoustic system. The highest point of the fort is the "Bala Hissar", which is located a kilometer away. The palaces, factories, water supply system and the famous "Rahban" cannon, within the fort are some of the major attractions.

It is believed that there is a secret underground tunnel that leads from the "Durbar Hall" and ends in one of the palaces at the foot of the hill. The fort also contains the tombs of the Qutub Shahi kings. These tombs have Islamic architecture and are located about 1 km north of the outer wall of Golkonda. They are encircled by beautiful gardens and numerous exquisitely carved stones. It is also believed that there was a secret tunnel to Charminar.

The two individual pavilions on the outer side of Golkonda are also major attractions of the fort. It is built on a point which is quite rocky. The "Kala Mandir" is also located in the fort. It can be seen from the king's durbar (king's court) which was on top of the Golkonda Fort.

The other buildings found inside the fort are :
Habshi Kamans (Abyssian arches), Ashlah Khana, Taramati mosque, Ramadas Bandikhana, Camel stable, private chambers (kilwat), Mortuary bath, Nagina bagh, Ramasasa's kotha, Durbar hall, Ambar khana etc.
This majestic structure has beautiful palaces and an ingenious water supply system. Sadly, the unique architecture of the fort is now losing its charm.
 
Taramati Mosque
The ventilation of the fort is absolutely fabulous having exotic designs. They were so intricately designed that cool breeze could reach the interiors of the fort, providing a respite from the heat of summer.

The Huge gates of the fort are decorated with large pointed iron spikes. These spikes prevented elephants from damaging the fort. The fort of Golkonda is encircled by an 11-km-long outer wall. This was built in order to fortify the fort.
Naya Qila (New Fort):-
Naya Qila is an extension of Golkonda Fort. The ramparts of the new fort start after the residential area with many towers and the Hatiyan ka Jhad "Elephant-sized tree" - an ancient baobab tree with an enormous girth. It also includes a war mosque. The local government plans to convert the area into a golf club.
Qutub Shahi Tombs:
The tombs of the Qutub Shahi sultans lie about one kilometer north of Golkonda's outer wall. These structures are made of beautifully carved stonework, and surrounded by landscaped gardens. They are open to public and receive many visitors.
Koh-i-Noor:-
The Koh-i-Noor (Persian for Mountain of Light; also spelled Kohinoor and Koh-i-nur) is a large, colourless diamond that was found near Guntur in Andhra Pradesh, India, possibly in the 13th century. According to legend, it first weighed 793 carats (158.6 g) uncut, although the earliest well-attested weight is 186 carats (37.2 g); it was first owned by the Kakatiya dynasty. The stone changed hands several times between various feuding factions in South Asia over the next few hundred years, before ending up in the possession of Queen Victoria after the British conquest of the Punjab in 1849.
In 1852, Prince Albert, the husband of Queen Victoria, unhappy with its dull and irregular appearance, ordered it cut down from 186 carats (37.2 g). It emerged 42 percent lighter as a dazzling oval-cut brilliant weighing 105.6 carats and measuring 3.6 cm x 3.2 cm x 1.3 cm.[3] By modern standards, the cut is far from perfect, in that the culet is unusually broad, giving the impression of a black hole when the stone is viewed head-on; it is nevertheless regarded by gemmologists as being full of life. As the diamond's history involves a great deal of fighting between men, the Koh-i-Noor acquired a reputation within the British royal family for bringing bad luck to any man who wears it. Since arriving in the country, it has only ever been worn by female members of the family.
Today, the diamond is set in the front of the Queen Mother's Crown, part of the Crown Jewels of the United Kingdom, and is seen by millions of visitors to the Tower of London each year. The governments of India, Pakistan, Iran and Afghanistan have all tried to claim ownership of the Koh-i-Noor and demanded its return at various points in recent decades. However, the stone's early history is lost in the mists of time, and the British government insists the gem was obtained legally under the terms of the Treaty of Lahore.
It is widely believed to have come from the Kollur Mine in the Guntur District of present-day Andhra Pradesh India, during the reign of the Hindu Kakatiya dynasty in the 13th century in the Bhadrakali Temple. It is however impossible to know where it was found. In the early 14th century, Alauddin Khalji, second ruler of the Turkic Khalji dynasty of the Delhi Sultanate, and his army began looting the kingdoms of southern India.Malik Kafur, Khilji's general, made a successful raid on Warangal in 1310, when he possibly acquired the diamond.
It remained in the Khilji dynasty and later passed to the succeeding dynasties of the Delhi Sultanate, until it came into the possession of Babur, a Turco-Mongol warlord, who invaded India and established the Mughal Empire in 1526. He called the stone the "Diamond of Babur" at the time, although it had been called by other names before it came into his possession. Both Babur and his son and successor, Humayun, mentioned the origins of this diamond in their memoirs, thought by many historians to be the earliest reliable reference to the Koh-i-Noor.

Shah Jahan, the fifth Mughal emperor, had the stone placed into his ornate Peacock Throne. In 1658, his son and successor, Aurangazeb, confined the ailing emperor at nearby Agra Fort. While in the possession of Aurangazeb, it was allegedly cut by Hortenso Borgia, a Venetian lapidary so clumsily that he reduced the weight of the stone from 793 carats (158.6 g) to 186 carats (37.2 g).[12] For this carelessness, Borgia was reprimanded and fined 10,000 rupees. According to recent research the story of Borgia cutting the diamond is not correct, and most probably mixed up with the Orlov, part of Catherine the Great's imperial Russian sceptre in the Kremlin

WHY DO FLOWERS HAVE FRAGRANCE?


WHY DO FLOWERS HAVE FRAGRANCE?
Whenever we pass through a garden during the spring the fragrance of flowers enchants us.Nature has endowed flowers with beauty,attractive colours,nectar and fragrance.Insects and flies get attracted towards the flowers and sit on them.And when they leave they carry with them pollen grains to other flowers

                Flowers have unique smells because they attract different pollinators. For example, bees, moths and butterflies tend to be drawn to sweet smelling flowers, like roses, whereas insects like dung flies are attracted to flowers that smell like rotting meat .
Brightly colored flowers attract different insects to come visit the flower. When insects like bumblebees perch on a flower's petals looking for nectar, pollen gets stuck to their bodies. When insects fly off to another flower, the pollen is transferred to the new flower.
                Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower's scent can have particular appeal to bees, and its bright colours may lure the bees in.
Different flowers contain  different  oils which give specific fragrance to flowers.As these oils gradually keep on evaporating ,the fragrance of the flowers spreads in the air.In fact, perfumes are prepared from the oils extracted from these flowers.
                There are various processes of making perfumes.In one process,flowers are kept in a pot through which steam steam is passed. The out going steme brings oil with it.This steam is passed through water .Thus the oil brought out by the steam starts floating on the water surface .This is then separated from water.There are other methods of making perfumes also.France produces maximum amount of perfumes.It has been found that one ounce of rose perfume is extracted from 110 kg of rose flowers.Flowers like rose, Raat Ki Rani,pandarus, lavender,jasmine,etc.,are generally use for making perfumes.

WHY DO BIRDS SING

WHY DO BIRDS SING

The Song of birds is one of the loveliest sounds in nature.Sometimes when we are out in -the country and we hear birds singing,it seems to us they are calling back and forth , that they are tellling one another somthing.The fact is that the birds do communicate with one another,just as many other animals do.Of cours ,at times sound of birds make are expressions of joy ,just as we make cries of 'oh!,,and ..Ah!..But for the most part,the sounds that birds make are attempts at communication .A mother hen makes sounds that warn her chicks of danger and causes them to crouch down motionless.Then she gives another call which collects them together.When wild birds migrate at night,they cry out.These cries make the birds together and help lost one return to the flock.But the language of the birds is language as we use it.We use words to express ideas,and these words have to be learned.Birds don't learn their language.it is inborn instinct with them.In one experiment,for example,chicks were kept away from cocks and hens so the could'nt hear sounds just as well as chicks had grown up with cocks with cocks and hens!
This dos'nt mean that birds can't learn how to sing.In fact,some birds can learn the songs of other birds.This is how the mockingbirds gets its name,If a sparrow id brought up with canaries, it will make great efforts to sing like a canary .If a canary is brought up with a nightingale,it give quite a good imitation of the nightingale's song.And we all know how a parrot can imitate the sounds it hears.So we must say that while birds are born with the instinct to sing,some learning takes place,too.
