The most famous landmark in Tiruchirapalli is the Rock Fort, a large outcrop of rock, 83 metres high. It is the only such outcrop in the otherwise-flat land of the city, and because of it Trichy is also called Rock City. On top of the rock is the Ucchi Pillayar Koil, a temple dedicated to the Hindu god Vinayaka (Ganesha), from where one can enjoy a panoramic view of Tiruchirapalli. The temple was also used as a military fort by the Nayaks for some time.
On the southern face of the rock are several beautifully-carved cave temples of the Pallava period. On the eastern side is Sri Nandrudayan Vinayakar Temple, with Ganesha as the main deity. A large-sized Ganesha and depictions of other rare deities can be seen in this temple, which hosts festivals every year during the Vinayaka Chathurthi (birthday of Ganesha). Many Carnatic musicians have given concerts in this famous shrine. Around the rock temple is a busy commercial region, specializing in textiles, known as Chatram. The Main Guard Gate is flooded on festive occasions such as Deepavali, Ramzan, Bakrid, Christmas, and Pongal.
