Referred to as simply the "Olimpo," this is the best venue in town for free cultural events. The beautiful porticoed cultural center was built adjacent to City Hall in late 1999, occupying what used to be a parking lot. The marble interior is a showcase for top international art exhibits, classical-music concerts, conferences, and theater and dance performances. The adjoining 1950s-style movie house shows classic art films by directors like Buñuel, Fellini, and Kazan.
The center also houses a planetarium with 60-minute shows explaining the solar system (narration is in Spanish); they run Tuesday through Sunday at 6 pm and Sunday at 10, 11, noon, 6, and 7—be sure to arrive 15 minutes early as nobody is allowed to sneak in once the show has begun.
