The Dominican monastery of Santo Domingo in Oaxtepec is located on a fairly steep hill over a pre-Hispanic ceremonial platform. For this reason, the atrium is not located in front of the church and is more elevated than the church. In the interior of the church, Gothic arches support the roof and the vault is decorated with floral motifs. There are two wood altarpieces from the 17th century. The monastery of Oaxtepec has pillars in the cloister with images of saints, and barrel vaults decorated with repeating motifs such as fleur-de-lis. The murals here have remnants of blue coloring, which is unusual but most have lost their color entirely. Most of the murals which have disappeared completely have been destroyed by humidity, which is mostly due to the lack of maintenance of the roof's drainage. The monastery's cloister has been converted into a museum, but only three of the halls are open to the public. It contains a modest collection of pre-Hispanic pieces and regional animals, insects and plants.
