This fort is situated approximately 6 km to the north east of the city Kanyakumari. Vattakottai Fort was erected in 18th century, and this was the last fort amongst the coastal forts built by the Travancore emperors.
The height of the walls of Vattakottai fort is nearly 25ft and the thickness of the walls is around 29ft on the front. The fort was built by De Lannoy, who was a Dutch naval officer.
The fort is made of stone and it includes rest rooms, watchtowers and weapon rooms. The walls inside the fort have engravings of fish design, which is supposed to be emblem of Pandyas. It is also said by the archaeologists that the fort was under the authority of Pandyas in the past.
