Thangassery Fort
Some limited standing ruins of an old colonial fort. You can see two different sides of the building, the first from the harbour side (where it is visible at some distance), and the second from the opposite side. The site is slightly overgrown so beware of snakes if you venture close. An auto-rickshaw from the Main Road bus stop cost ₹50.
A modern lighthouse in a historic Christian quarter that is possible to climb in the afternoons. Best to combine with the Thangassery Fort, as the two sites are in easy and shaded walking distance.
