The simple whitewashed parish church on the central plaza has been rebuilt many times since its 16th-century foundation — pirate raids, hurricanes, and earthquakes have all flattened earlier versions — but the current building is mostly 19th-century, with a single bell tower and a modest barrel-vaulted nave. The interior is plain: white walls, dark wooden pews, a small altar.
Despite its modesty, the church is a focal point of the town. Sunday mass fills the building; the plaza outside, with its kiosk, mango trees, and benches, is the social heart of Trujillo and a good place to sit with a baleada and watch the town go by. Free entry outside of services.
