Construction from the beginning of 1380, with the support of João Afonso Telo and his wife D. Guiomar de Vilalobos, was only completed around 1420.

It is a large and beautiful temple characteristic of the full Portuguese Gothic, with three naves defined by pointed arches, based on two wings of columns surmounted by capitals decorated with vegetal motifs and a few, very few, with anthropomorphic motifs. The lighting is done through ogival windows and transports us to a space that reflects the idea of the time, "God is light".

The facade with the rose window and the flaming portal are in perfect harmony within the profusion of decorative elements of the flaming Gothic.
