at Ek Balam, the archaeological zone in Yucatan. These have been uncovered by archaeologists during the past 15 years. When found (uncovered of earth, rocks, and trees), they were in this excellent state of preservation. No restoration was needed, we are told. This is seen on the upper level to which I climbed.
