Yagul was built the way water runs: downhill. Its main structures and buildings were laid out on different levels, following the natural slope of the hill from north to south. Archaeologists usually group them into three areas: the Civic Center, the Fortress, and the Residential Zone. Start with the civic heart, which sits at the foot of the hill and stands out for its integrity. This was the administrative and religious center of Yagul: a large platform holding a group of buildings, typically arranged around a central courtyard ringed by columns and rectangular rooms. Within the palace complex, described as an artificial platform with six courtyards surrounded by rooms that have central doorways, one room contains a monolithic throne, and others hold funerary chambers. Because of that array of courtyards, it is considered the largest palace among the archaeological sites of the Valley of Oaxaca, and it was probably a gathering place for the community's leaders. Higher up the slope, the Residential Zone tells a more intimate story. It consists of six residential compounds with very restricted entrances, their rooms framing square courtyards, and materials found in those rooms show they were used as homes. The Fortress, meanwhile, is a reminder that this was contested ground, in an era when disputes over control of the region sparked constant wars and pushed cities to build fortifications.
