The region around Oaxaca is home to several thousand archaeological sites, with more being discovered all the time. The remains of Zapotec and Mixotec civilization can be seen at Monte Albán and Mitla, the two most popular and well-known sites in the area. Some of the Monte Albán artifacts are now stored in the house of Rufino Tamayo, which also has a collection of pre-Hispanic art (address: Morelos 503). Other museums that display artifacts from the Monte Albán site are the Centro Cultural Santo Domingo (Alcalá y Gurrión) and the Instituto Nacional de Antropología e Historia (at the Zona Arqueológica de Monte Albán). A few other archaelogical sites that are perhaps not as well known, but still worth a visit, are Yagul, Lambiteco and Dainzú.
There are numerous art museums in the city. The Museo de Arte Contemporáneo de Oaxaca at Alcalá 202, started by leading Mexican artist Francisco Toledo, has 6 permanent gallery rooms and 8 rotating displays, dedicated to nationally celebrated artists. Graphic art, on the other hand, is mostly housed in the Instituo de Artes Gráficas, which has a collection of over 5000 works from around the world.
The Casa de Cultura Oaxaqueña is the city’s main cultural center; it holds art workshops, dances, concerts and stage performances (González Ortega 403). There is also a religious museum in the Basilica de Nuestra Señora de la Soledad (Independencia 107) and a historical house-turned-museum at Garcia Vigil 609, former home of Benito Juarez.

A small museum of special interest is the Philatelic Museum on Reforma next to the Ethnobotanical museum (a part of the Sto Domingo church complex). The museum is free and has displays of postage stamps as well as old postal items. There is also a small shop where you can buy stamps, usually without a wait, as well as cards and other items. They are quite helpful in telling you the postage needed for various countries. You can leave cards and letters to be mailed inside the store, where they are picked up regularly, or in the mailbox outside the museum. There are handstamps inside the display area right across from the shop, which kids or anyone can use to stamp envelopes. Just walk in and stamp on your card or envelope, but make sure you aren't stamping where the postmark will go on the postage stamp. Inside the museum there is also a nice bathroom , which can be nice for a traveler not near their hotel or B&B. The museum is call MUFI in the spanish acronym and has a website
