Warangal is located on northern Andhra Pradesh State lies along the Chennai-Kazipet-Delhi rail route. Warangal was the ancient capital of the Kakatiyas, an Andhra dynasty that flourished in the 12th century AD. The city stands out for its beautiful lakes, temples and wildlife. It is very rich in antiques and relics. Warangal's fort, lying southeast of the present-day city, was once surrounded by two walls, traces of the outer wall remain, as do the four stone gateways ('sanchar') of the inner wall. A thousand-pillared temple, built in 1162, is located within the city itself. Warangal is now a commercial and industrial center. Prola Raja of the Kakatiya dynasty founded the place in the 12th century AD, but some identify it with Worakalli, the capital of the Adeva Rajas of Tuluva Andhra or Telengana in the 8th century AD. Warangal or Varankal is believed to be the Korun Kula of Ptolemy, while another name is Akshalinagar, evidently Yeksilanagar mentioned by Raghunath Bhaskar in his Aravachan Kosh. The ancient name of Warangal was known to be Orugallu or Omtikonda on account of huge boulder like hillock situated near the swayambhu Siva Temple and is also called "EKASILANAGARAM". In course of time, it was called as "Orugallu", and finally known as Warangal. Warangal has many places, which attracts tourists in large number.
