The Governor’s Palace, with its magnificent facade nearly 100m long, is arguably the most impressive structure at Uxmal. The buildings have walls filled with rubble, faced with cement and then covered in a thin veneer of limestone squares; the lower part of the facade is plain, the upper part festooned with stylized Chaac faces and geometric designs, often lattice-like or fretted.
Other elements of Puuc style are decorated cornices, rows of half-columns (as in the Casa de las Tortugas) and round columns in doorways (as in the palace at Sayil).
Researchers recently discovered some 150 species of medicinal plants growing on the east side of the palace. Due to the high concentration of plants growing there it's believed they were cultivated by the Maya to treat stomach infections, snake bites and many other ailments.
