Founded by Countess Mumadona in the 12th century and rebuilt four centuries later, the beautiful Largo da Oliveira is dominated by this convent church.

　　The monument outside the church is a Gothic canopy and cross, reputedly marking the spot where the great Wamba the Visigoth, victorious over the Suevi, drove his spear into the ground beside an olive tree and refused to reign unless a tree sprouted from the handle. In true legendary fashion, it did just that.
