Detail of the southern façade of the Nunnery's southern building. To approach this complex, which was probably off-limits to all but the highest status people of Uxmal, one has to ascend a stairway of broad steps. An elegant access arch, which pierces the building from side to side, still affords access to the inner court. This southern building probably served two distinct functions, as it has rooms opening both to the inside and to the outside of the quadrangle: those opening on the inner court would have presumably been used to deal with affairs restricted to the few, while the rooms in its outer façade may have been used for dealing with a broader public.
