Igreja de São Sebastião (Sao Sebastiao Church), Lagos

Saint Sebastian Church is a modest yet historically significant religious building located in the historic centre of Lagos, slightly removed from the main tourist routes. Its origins reach back to the 14th century, when it was first built as a hermitage dedicated to Our Lady of the Conception. Two centuries later, in response to outbreaks of plague, the building was rededicated to Saint Sebastian, a saint widely invoked for protection against disease. The church was enlarged in 1520 by order of King Manuel I and formally reconsecrated to Saint Sebastian, marking its transition from a small hermitage into a parish church.

Architecturally, the church reflects multiple phases of construction and rebuilding. It consists of three naves separated by arches supported by Doric columns. The main entrance features a late Gothic portico, complemented by a Renaissance side portal. Additional side altarpieces were added in the 16th century, while blue azulejo tiles were installed in the nave during the 17th century. The main altar is fashioned with gilded woodcarving. Adjacent to the church is a small Bones Chapel, where neatly stacked skulls line the walls.

The church suffered severe damage during the earthquake of 1755, which destroyed the tower and tribune and forced the parish headquarters to relocate. The tower was rebuilt by 1828, with a clock added, and the structure endured further damage during the 1969 earthquake. Inside, visitors can see a moving statue of Our Lady of Grace, who, together with Saint Francis, is believed to continue watching over the parish.
