Vattakottai Fort, as the name goes, is a circular fort located about 6 kms to the north-east of Kanyakumari town, in Agasteeswaram taluk. The Fort, built entirely of stone, consists of watchtowers, rest rooms and a few weapon rooms. Many of the walls within the fort have carvings of a fish-like motif on them. Vattakottai Fort commands a picturesque view of the calm waters of the Arabian from one side of the parade ground of the fort, and the rough waters of the Bay of Bengal on the other. Another notable feature of the Fort is that near its site, there is a beach consisting entirely of black sands, located about 7 kms from the Kanyakumari town.
