Building from the XIX century built by the architect Carlos Z. Flores. The original intention was to make a building that would cover an entire block to keep the seat of the state government, however, only a quarter of the building was built when the City lost its capital status in 1892. It is the best example of the neoclassical style in the Catalog of Vignola, which can be seen in its set of round arches. The building has 2 floors with a portal on the ground floor, the layout and distribution is like that of a traditional Town Hall.
This building is currently the MUSAC, Museum of San Cristóbal de Las Casas.
