Museo de Historia del Arte (MuHAr)
In the Palacio Municipal (an ambitious name for this unremarkable brick city hall) you'll find the Museum of Art History, which has the country's best collection of pre-Columbian and colonial artifacts. You'll also find Greek, Roman, and Middle Eastern art, including ceramics and other antiquities. On the street level is the Biblioteca de Historia del Arte (Art History Library), worth a stop if you're a student of the subject matter.
