Tŵr y Felin
SM 756 250 Close to the old windmill was a Second World War HFDF directional radio aerial - a three-storey timber tower protected by a blast wall.
This was part of a system for tracking British warplanes, either helping them to return to their airfields in Pembrokeshire or pinpointing them if they were forced to ditch at sea. The blast wall still stands in a field near the TYF centre.
