Thought to be the most representative of a cluster of colonial churches in the old town, the Church of Santa Clara was built between 1629 and 1674 as a part of the Poor Clares Convent. As one of the city’s oldest churches, it is lavishly decorated with 112 paintings and 24 sculptures dating back to the 17th and 18th centuries. It’s a museum church run by the municipality, so not free to enter, but is certainly worth every peso.
