Popayán is a city in western Colombia, southwest of Bogotá. It's known for its whitewashed colonial buildings and as a religious center with popular Holy Week processions. The city's many churches include the domed, neoclassical Cathedral Basilica of Our Lady of the Assumption and the 17th-century Church of La Ermita. In the city’s heart, tree-shaded Caldas Park is home to a 17th-century clock tower.
