The Oaxaca Ruins Wiki is an expanding companion to the Monte Albán Wiki, dedicated to documenting the vast network of archaeological sites across the state of Oaxaca. From early Formative centers like San José Mogote and Yucuita to Classic-period cities such as Mitla, Yagul, and Lambityeco, this collection brings together the principal Zapotec, Mixtec, and related sites that shaped Mesoamerican civilization. Each entry provides cultural background, architectural highlights, and sourced references drawn from INAH, UNESCO, and peer-reviewed research. Our aim is to present a clear, trustworthy, and interconnected view of Oaxaca’s ancient heritage.
