Great Compound
It probably means something like "large mound of earth." It borders the Street of the Dead for 630 meters and is directly opposite Ciudadela. Although it is a large area, no detailed excavations have been carried out.

The few that have been reported are:。
1. 630 x 400m.
2. There are traces of 14 non-residential buildings, but no internal partitions can be confirmed.
3. There is a 230 x 265m plaza in the center. There are no traces of a temple around it. Normally, plazas can only be entered from one direction, but there are unstructured "entrances" on both the east and west sides.
4. There is a tunnel dating from between 1 AD and 100 AD, in which 12 bodies, possibly those of sacrifices, have been found.
5. Between 100 AD and 250 AD, the entire layout was completed on a 630 x 400m, 1m high platform.
6. Between 250 AD and 350 AD, the entire floor was plastered.
No photographs or floor plans of the tunnel have been found, and the surrounding area is also unknown, but the sacrifices indicate religious activity. It is possible that the area was used as such until 100 AD, and that it was used as a secular area after that.

The layout diagram fits into the red box above. So, what was once the central square is now occupied by the road from the roundabout, a parking lot, a ticket office, a souvenir shop, and a closed restaurant.
Head north on the east side of the Great Compound and turn onto the west side lane just before the San Juan River.
