 The city was founded in 1525, but it did not gain municipal status until 1932.Today, the municipality is poor and agricultural, but is home to several unique traditions such as the Santiago Tuxtla Fair and the Acarreo de Niño Dios, when images of the Child Jesus are carried in procession several times during the Christmas season.It is also home to the Museo Regional Tuxteco (Tuxtla Regional Museum) which houses much of the area's Olmec artifacts, including a number of colossal heads and other monumental stone works.
