The monastery of La Concepción in Zacualpán was built by the Augustinians. It has conserved much of its original layout, including the original layout of gardens and homes that surround it. Water here is provided by the melting snows of Popocatepetl. The baptistery has an arch and in its wall are the remains of a painted altarpiece. Its Rosario Chapel has other small Baroque altarpieces of great quality. There is a stone baptismal font made by indigenous hands and a series of chapels in the atrium which date to the 18th century. There is also a series of artworks from the same time period.
