The San Diego Pro-Cathedral stands at the centre of Silay, its cream and ochre facade facing the plaza in the manner of Spanish colonial churches throughout the Philippines. The current structure was built in the early nineteenth century on the foundations of an earlier church and has the thick walls and small windows typical of earthquake-resistant colonial construction.
Inside, the nave is largely unaltered, with a painted ceiling, carved wooden pews, and side altars housing antique santos (carved saints) accumulated over centuries of parish life. The church is still an active place of worship, so dress modestly and keep noise down during services. The bell tower alongside the church is a separate structure — worth walking around for the view over the plaza and the old commercial district of Rizal Street.
