The cathedral was built in 1553 and reconstructed in 1773. Its elaborate 18th-century baroque facade is an excellent example of the Oaxacan style. The central panel above the door depicts the assumption of the Virgin. Note the heavy, elaborate frame around the picture and the highly stylized wavelike clouds next to the cherubs -- these elements, repeated in other churches in the region, are telltale signs of Oaxacan baroque. An uncommon and quite lovely detail is how the Virgin's cape and its folds are depicted in angular lines and facets. The cathedral's interior is not as interesting as its exterior because it was plundered during the Reform Wars.
