The Convento de Corpus Christi stands on the hillside above the Gaia waterfront, its ochre-yellow façade visible from across the Douro. Founded in the early fourteenth century and rebuilt in the seventeenth, the convent is one of the significant Baroque religious buildings on the Douro estuary, with an elaborate main entrance and a church interior that retains its original gilded woodwork and azulejo panels.
The convent is still occupied by Dominican nuns and therefore not fully open to the public, but the church itself can usually be visited during set hours. The interior is impressive — a single nave with side chapels, the walls covered in blue-and-white azulejo panels depicting scenes from the life of various saints, and a gilded retable behind the main altar. The quality of the tilework is among the best in the area.
Worth seeking out if you are interested in Portuguese Baroque ecclesiastical architecture; most visitors to Gaia overlook it entirely in favour of the port lodges below.
