At a distance of 6 kms north-east of Kanyakumari (on NH7), Vattakottai (Circular Fort) is a granite fort built by Marthanda Varma to serve as defence for Nanjil Nadu. This town is also having a nice beach.
It is rectangular in shape and covers an area of about three and a half acres. The fort is enclosed by walls 25 to 26 feet high, including the parapet, 29 feet thick at the front, 18 feet at the corners and 6 feet at the rear. The small river by the side of the fort, and the green vegetation all around add to the scenery of the fort and has now become a holiday resort and picnic centre.
It is said that there is a subway or tunnel about four feet width, supposed to connect the Padmanabhapuram palace. Now the tunnel has been closed.
