Igreja Matriz de São Sebastião is a 17th-century colonial church located in the historic center of São Sebastião, São Paulo. Construction began in 1636 and concluded in 1652, making it one of the oldest religious structures in the region. The building features thick masonry walls made of stone, lime, and whale oil, a common colonial construction technique in coastal Brazil. It houses an image of Saint Sebastian, the city's patron saint, crafted in Portugal. The church underwent significant structural restoration in the 20th century to preserve its original taipa and masonry characteristics. It remains a central site for local religious festivals, including the Festa de São Sebastião in January. The interior retains a traditional design with a single nave and a main altar area.
