The Cathedral of Santiago Apóstol dominates Boaco's central park and is the most imposing building in the city. Built in the colonial style with a pale façade and twin bell towers, it sits above the main square and is visible from much of the surrounding town. Inside, the proportions are simple and the decoration modest — this is a working parish church, not a showpiece.
The square in front of the cathedral is the social centre of Boaco, with benches, trees, and the inevitable cluster of mototaxi drivers. In the evening it fills with families and vendors. If you arrive at dusk, the cathedral's towers catch the last light nicely.
