ROCK FORT

Tiruchy's most famous landmark is 83-m high rock which is the only outcrop in the otherwise flat inland of the city. The most amazing fact about the rock is that it is one of the oldest in the world. The sheer abruptness of its rise is an attention grabber. But the actual centre of attraction is not the fort itself, of which very little remains, but the temple at the summit. 420 steps carved out of rock lead to the top where there are inscriptions dating back to the 3rd century B.C Hardly anything remains of the ramparts but the Main Guard Gate is still intact The fort played an important part during the Carnatic wars and according to an inscription, mainly contributed to lay the foundations of the British empire in India. A top the rock is the Uchipillaiyar Koil, a temple dedicated to Lord Vinayaka from where one can enjoy a panoramic view of Tiruchy. A flight of steps leads to the Mathrubutheswarar or Thayumanaswami temple. Dedicated to Lord Siva where the lingam is the projection of the rock itself. There are two Pallava cave temples that have beautiful sculptures of the 6th and 7th centuries. At the foot of the Rock Fort is a tank and a pavilion which is used during the float festival of the temple. Facilities for boating in the tank is available. Near the tank is the house where Robert Clive lived when he was in Tiruchy . The house is now part of Tiruchy's famous St.Joseph college. The 18th century Christ church build by Schwartz of Denmark is nearby .
