[1] The church was built in the second half of the 12th century by the provincial master of the Order of the Knights Templar in Portugal, Gualdim Pais.
Gualdim Pais is buried in the church, and his original tomb slab, dated from 1195 and bearing a gothic inscription, is still preserved inside.
The main façade has a beautiful rose window and a simple portal with several archivolts, and is flanked by a free-standing bell tower.
On the left side nave, in front of the chapel displaying the statue "Virgin Mary" there is a slab carved with the arms of two (2) families whose faded Latin inscription reads, immediately under the arms, "T.DA.CUNHA" appearing to indicate that one of the persons buried under it was a relation of the famous commander Tristão da Cunha.
