The ruins of Alamparai Fort (also called Alampara) lie near Kadappakkam in India,[1] 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.

[4][5] Alamparai is mentioned in several places in the diaries of Ananda Ranga Pillai, Dubash to Dupleix in French India.

The other contemporary ports were Pulicat, Madras, Mylapore, Sadras (12 km from Mahabalipuram), Pondicherry, Cuddalore, Porto Nova, Tharangambadi (Tranquebar), Karaikal, and Nagapattinam.

The Tamil Nadu Tourism Development Corporation (TTDC) listed the fort as one of twenty lesser known tourist spots in the state.

Portions of Pithamagan, a 2003 Tamil film, starring popular actors Suriya and Vikram, was shot in the fort.
