Monuments

Part of the area classified by UNESCO as World Heritage in December 1996, the Monastery of Serra do Pilar is the architectural landmark of Gaia. The interesting church and cloisters are laid out according to a circular design unique in Portugal.

The convent built in the 16th century belonged to the Order of Saint Augustine. The church is characterised by a circular shape, a replica of the Church of Santa Maria Redonda in Rome, and is covered by a hemispheric vault with a narrow balcony running its full extent. It took 72 year to complete due to the lack of funding and the political turmoil of those times – with the kingdom of Portugal having fallen to neighbouring Spain. One legacy of that event was the adoption of a Spanish saint for the monastery, Our Lady of Pilar.

In 1832, during the Siege of Oporto, its military value was made use of with the convent swiftly turned into an improvised fort. At the beginning of the 20th century, the monastery was used for military barracks and remains under the tutelage of the Serra do Pilar Artillery Regiment.

Within, the Church features some impressive carved gold leaf altars with Solomonic columns. There are also 18th century, polychrome wooden carvings of the saints Eulalia, Apollonia and Augustine.

In front of the church, there is a wonderful view point taking in the full splendour of the city of Oporto and the river Douro below.
