The Manora fort is situated 65 km (40 mi) away from Thanjavur, Tamil Nadu, India. The fort was built by Maratha ruler Serfoji II in 1814–1815 to commemorate the successful advance of the British over Napoléon Bonaparte. It is an eight-storeyed, hexagonal tower, which is 23 m high overlooking the Bay of Bengal. The fort derives its name Manora, from the word Minaret.
