Directly above Cwm yr Eglwys beach is the remains of the old 12th Century church of St. Brynach. Now only the west wall remains and the graveyard, Cwm yr Eglwys church was destroyed during a violent storm in October 1859.
This is quite significant date in history, for who would have thought that a little village like Cwm yr Eglwys would have been the catalyst which marked the beginning of official weather forecasting in this country.
Only the west wall of the St Brynach’s church remains standing along with the gravestones of local folk buried centuries ago. This church is now the focal point of this very picturesque Pembrokeshire cove.
