San Sebastián, Catholic church in Lima District, Peru

San Sebastian is a church building in Rococo style located at the corner of Ica and Chancay streets in Lima's historic center. The structure displays a pink and white facade, and inside it houses religious artworks including a notable main altarpiece created in the 18th century.

Founded in 1554, San Sebastián is Lima's third parish, after the Sagrario (1535) and Santa Ana (1550). The church is traditionally linked to the baptisms of Rose of Lima, Martin de Porres, Francisco Bolognesi, José Santos Chocano and José María Eguren. The design is often misattributed to Francisco Becerra, who only reached Lima in 1582, 28 years after the founding.

The parish is the third oldest in Lima, founded in 1554 after El Sagrario (1535) and Santa Ana (1550). Its pink-and-white front faces Jirón Ica in the old Monserrate quarter, later called Cuartel Primero. The small parish house closes off the plazuela, which keeps its 1888 fountain.

The church sits at a central corner in the old city and is easy to reach on foot when exploring this area. Visitors should know this is an active place of worship, so appropriate dress and respectful conduct are expected.

On the church's balcony sits an old lamp that once served as street lighting in Lima's early days. This small detail shows how the city kept its nighttime streets functional before modern lighting systems.
