The chapel of the old convent of Nossa Senhora da Pena still has the original configuration of the 16th century. The small nave has a vaulted warhead and 16th century tiles. Noteworthy is the altarpiece made by the Frenchman Nicolau de Chanterene (1529-1532) and the stained glass window of the neo-Gothic window (1840-1841), commissioned by D. Fernando from a famous family of stained glass builders in Nuremberg, the Kellners.
