The San Andres Tuxtla city fathers had the foresight to try to save some of the city history and converted several early twentieth century homes into a cultural center in 1987, which also now functions as a small museum.
The center is well used by locals for regular cultural events. Although the museum may not be a "must" visit for tourists, it will excite pre-hispanic archaeology buffs with a few unique artifacts.
It is located down from the central plaza to the central market, then 2 blocks to the left (inland).
