Rock Fort Temple Tiruchirappalli Rock fort is a historic fortification and temple complex built on an ancient rock. It is constructed on a 83 meters (272 ft) high rock that may date to over one billion years ago. There are two Hindu temples inside, Ucchi Pillayar Temple, Rock fort and the Thayumanaswami Temple, Rock fort. Other local tourist attractions include the famous Pallava-era Ganesh temple and the Madurai Nayak-era fort. The fort complex has witnessed fierce battles between the Madurai Nayaka’s and Adil Shahi dynasty of Bijapur, Carnatic region and Maratha Imperial forces. The fort palace also witnessed the transfer of power from Queen Meenakshi to Chanda Sahib, as he ruled in conjunction with the alliance with the Kingdom of France. He lost this command when his uncle, the Nawab of the Carnatic along with the British, seized the fort after the Carnatic wars. This enabled the British to gain a foothold in Tamil Nadu and later all of South India. In modern times, the fort is maintained and administered by the Chennai Circle of the Archaeological Survey of India. The fort is one of the prominent tourist destinations in Tamil Nadu.
