The monastery is situated on an outcrop overlooking the Dom Luís I Bridge and the historic centre of Porto.

The Monastery of Serra do Pilar is located in the parish of Santa Marinha e São Pedro da Afurada in the historic centre of Vila Nova de Gaia.

[3] Serra do Pilar's military importance first became evidenced during the Peninsular War when it was used by General Arthur Wellesley to launch a surprise attack on the French across the Douro, and retake Porto.

[1] The monastery's prominent location acted as the only Liberal stronghold on the south side of the Douro during the Siege of Porto.

Since the late 20th century the monastery and grounds have been open to the public and the church continues to hold Sunday Mass.
