The history of this Benedictine monastery can be followed back to the 900s.
It was was in decline during the Reconquista before being resuscitated in the 1200s.
The consequence of those two phases is a blend of Romanesque and Gothic architecture.
The facade is a marvel, with a portal below five archivolts that have intricately sculpted capitals.
Above this is a striking rose window with simple circular tracery.
The big story though is inside at the tomb of Egas Moniz.
He was the preceptor (religious teacher/mentor) for Portugal’s first king Afonso Henriques.
On the sides of the tomb are high reliefs showing Moniz’s journey to the court Alfonso VII of León.
