The Chiapas Regional Museum (Calzada de los Hombres Ilustres s/n, Prolongación 5a Nte., tel. 961/613-4479, 9 a.m.–6 p.m. Tues.–Sun., US$4) has fascinating exhibits that walk visitors through Chiapanecan history, from the Protoclassic era to the present.
The ground floor—which has an unfortunate resemblance to an airplane hangar—has a superb collection of Maya artifacts, arguably the finest in the state. A separate wing houses an exhibit on the colonial and republican era and boasts a collection of Chiapanecan fine art. Signage is mostly in Spanish, with intermittent English translations.
