The Rock Fort Temple, perched 83m high on a massive outcrop, lords over Trichy with stony arrogance. The ancient rock was first hewn by the Pallavas and Pandyas, who cut small cave temples on its south side, but it was the war-savvy Nayaks who later made strategic use of the naturally fortified position. Reaching the top requires climbing over 400 stone-cut steps.
From NSB Rd on the south side, you pass between small shops and cross a street before entering the temple precinct itself, where there's a shoe stand. You might meet the temple elephant here. Then it's 180 steps up to the Thayumanaswamy Temple, the rock's biggest temple, on the left (closed to non-Hindus); a gold-topped tower rises over its sanctum. Further up, you pass the 6th-century Pallava upper cave temple on the left (usually railed off); on the left inside is a famous Gangadhara panel showing Shiva restraining the Ganges with a single strand of his hair. From here it's another 183 steps to the summit's small Uchipillaiyar Temple, dedicated to Ganesh.
The views are wonderful, with eagles wheeling beneath and Trichy sprawling all around.
