Towering over everything else in the town, is the former monastery of San Juan Baustista (John the Baptist). This monastery is part of the series of monasteries near the Popocatepetl volcano which was declared a World Heritage Site in 1994. Today only the church portion retains its original function and serves as the parish church for the municipality. The patron saint of the town is John the Baptist, whose feast day is celebrated on 24 June.
