Erukkalampiddy Ancient Survey Tower in Mannar (මන්නාරම එරුක්කලම්පිටිය පැරණි මිනුම් කුළුණ)
A damaged survey tower is found on the northern coast of Mannar Island unknown by many travellers. It lies off a bare strip of sand on a beach covered with thorny bushes. The tower stands on a square base. On top of it is two cylindrical segments, the top one smaller than the bottom. If it had a had a 3rd column at the top, it’s not visible now.
