Slideshow with my own photos taken during the trips to Mexico. Mitla is the second most important archeological site in the state of Oaxaca in Mexico, and the most important of the Zapotec culture. However, what makes Mitla unique among Mesoamerican sites is the elaborate and intricate mosaic fretwork and geometric designs that cover tombs, panels, friezes and even entire walls. These mosaics are made with small, finely cut and polished stone pieces which have been fitted together without the use of mortar. No other site in Mexico has this (Wikipedia).
