Half way through my 16 candidates is Monte Alban, just down the road from yesterdays candidate, Arbol del Tule. And again, wonderful scenery surrounds a fabulous set of ruins with an excellent museum and pretty good café/restaurant.
From Wiki: Monte Albán is a large pre-Columbian archaeological site in the southern Mexican state of Oaxaca. The site is located on a low mountainous range rising above the plain in the central section of the Valley of Oaxaca where the latter’s northern Etla, eastern Tlacolula, and southern Zimatlán/Ocotlán (or Valle Grande) branches meet. The present-day state capital Oaxaca City is located approximately 9 km east of Monte Albán. Besides being one of the earliest cities of Mesoamerica, Monte Albán’s importance stems also from its role as the pre-eminent Zapotec socio-political and economic center for close to a thousand years. Founded toward the end of the Middle Formative period at around 500 BC, by the Terminal Formative (ca.100 BC-AD 200) Monte Albán had become the capital of a large-scale expansionist polity that dominated much of the Oaxacan highlands and interacted with other Mesoamerican regional states such as Teotihuacan to the north (Paddock 1983; Marcus 1983). The city had lost its political pre-eminence by the end of the Late Classic (ca. AD 500-750) and soon thereafter was largely abandoned. Small-scale reoccupation, opportunistic reutilization of earlier structures and tombs, and ritual visitations marked the archaeological history of the site into the Colonial period.
