This former Dominican monastery is Tehuantepec’s Casa de la Cultura . It bears traces of old frescoes and has modest but interesting exhibits of traditional dress, archaeological finds, historical photos, religious regalia and the like. You may need to ask for some of the rooms to be opened. The last Zapotec king, Cosijopí, provided the funds for its construction in the 16th century, at the urging of Hernán Cortés. Staff also provide excellent tourist information.
