The Church and Convent of Saint Francis of Assisi is Trinidad's most distinctive landmark, its pale yellow bell tower rising above the town's red-tile rooftops and visible from well outside the city. The current building dates from the 19th century, though a convent has occupied this site since the 17th century. The church itself now houses the Museo de la Lucha Contra Bandidos, dedicated to the revolutionary period's campaign against counter-revolutionary groups in the Escambray Mountains in the 1960s.
The main reason to visit is the tower: the climb is steep and narrow, but the view at the top is the best in Trinidad. The town spreads below — you can read its street plan clearly, trace the colonial grid as it gives way to the less ordered neighbourhoods beyond, and see across to the sea on a clear day. The Escambray Mountains are visible to the north. Allow twenty minutes to climb and look.
