In the 16th century, when Lima was young, Catholic congregations were allotted sections of the city to build their monasteries, convents, and churches in honor of various patron saints. Most of these historic sites remain to this day, and they are worth a visit whether or not you are religious. The Church of San Francisco (Basilica y Convento de San Francisco) is one of the grandest and best-preserved of these structures. Inside and out, the building is richly decorated with artwork in the baroque and rococo styles. Deep within the basilica, you can walk through the quiet cloisters of the convent, where an overwhelming atmosphere speaks to the ages. This church is also famous for its catacombs, which formed a significant part of Lima's original cemetery infrastructure. Hire a tour to explore all the grandeur and mystique of this colonial church.
