Uxmal is the most well preserved of all of the Mayan cities. It is located in in the Puuc Hills of Yucatán Peninsula, Mexico and was built around 850-925 AD.
Unlike most other Mayan towns, Uxmal is not laid out geometrically. The town is organized in relation to the direction of rising and setting of Venus. Most of the buildings are oriented in the north-east axis.
The Governor’s Palace is constructed in such a way that it is angled away from the adjacent buildings. When observed it was found that the palace’s central doorway is aligned with the direction of Venus. This alignment corresponds approximately to the southernmost rising of Venus and much more precisely to the northernmost setting of Venus; both phenomena occur once every eight years.
The Pyramid of the Magician: The western staircase of the pyramid is situated so that it faces the setting sun on the summer solstice.
