180 KM Ride Alamparai fort built late in 17th century.

The ruins of Alamparai Fort (also called Alampara) lie near Kadappakkam in India, a village 50 km from Mamallapuram on the land overlooking the sea. Constructed in the late 17th century during the Mughal era, the Alamparai Fort once had a 100-metre long dockyard stretching into the sea, from which zari cloth, salt, and ghee were exported. During 1735 AD it was ruled by Nawab Doste Ali Khan. In 1750, for the services rendered by the famous French commander Dupleix to Subedar Muzaphar Jung, the fort was given to the French. When French were defeated by the British, the fort was captured and demolished in 1760 AD. More recently the structure was damaged in the 2004 Indian Ocean earthquake.
