The Museo Nacional del las Culturas de Oaxaca is the city’s finest museum. Housed in the former monastery of the Iglesia de Santo Domingo, the museum is dedicated to the preservation of Oaxaca's cultural and historical heritage, exhibiting many of the state's most important objects of art, artifact, and antiquity, spanning the pre-Columbian to the modern eras.
Among the museum’s extensive collection of exhibits are the priceless Mixtec artifacts of gold and jewelry excavated from Tomb 7 of Monte Albán, considered one of the most important archeological discoveries in México. Another important collection is the Francisco Burgoa Library, an archive of 23,000 historical books and documents dating back to 1484. All the descriptions of the exhibits are in Spanish, although an excellent audio guide in English can be rented for Mex$50 (Spanish Mex$40).
Even if the museum’s exhibits hold no interest for you, the architectural and artistic beauty of the early 17th-century ex-monastery housing them is reason enough to visit. Just north of the main entrance to the Iglesia de Santo Domingo, the ex-monastery’s long, tunnel-like main portal opens to a spacious cloister, two stories high, ringed with arcades fronting walks covered with thick, sturdy rib vault ceilings, a robust fountain at its center. On the north side of the cloister, a wide double staircase leads up a vestibule, its surfaces covered in painted reliefs and gilded stucco ornamentation, while upstairs, next to the entrance to the Iglesia de Santo Domingo’s choir loft, the dome and walls of the old friars chapel are covered in painted reliefs and gilded stucco ornamentation as well.
