The structures in the city of Tenochtitlan included temples, palaces, and platforms. Elites lived in palaces, which were called
tecpans. The word tecpan is often used as a shorthand for many different types of palaces, regardless of any special functions individual structures may have had. "Most commonly, the term [tecpan] meant the home of a hereditary lord, and it also took on associated meanings, such as the seat of government, place of riches and art, and idyllic retreat amidst scenery and diversions". Aztec palaces consisted of three main types: Administrative palaces, mansions of wealthy nobles, and pleasure palaces and retreats. Administrative palaces served as the location for local government, as well as the residences of local rulers. The focal point of these structures was a large courtyard near the entrance of the building, surrounded by suites that served various purposes. The mansions of wealthy nobles were used solely as residences, and were constructed in accordance with Aztec sumptuary laws. Pleasure palaces and retreats served many purposes, ranging from add-on structures at religious shrines to more opulent structures, such as
Nezahualcoyotl's baths, located at
Texcotzingo. According to Gary Feinman, Mesoamerican temples were typically rectangular structures with one entrance, located on one of its long sides. The structure of the temple was generally an elevated or shortened pyramid mound. They often consisted of two or more rooms, with an outer and inner chamber, the inner chamber being seen as more sacred. While rectangular pyramids could be dedicated to a wide range of gods, circular pyramids could only be dedicated to one god,
Ehecatl, who represented wind in Aztec culture. Urban designers in the Aztec period were known for placing small altars in significant locations. Some of these altars were believed to be bases for skull racks used to display victims of sacrifice. Others may have been dedicated to female fertility and curing, areas commonly associated with the
tzitzimitl deities in Aztec culture. Still, others may have served as offerings to the god Tezcatlipoca. Additionally, ball courts were a very popular construction of architecture used to play the ancient Mesoamerican ball game. Usually the ball court was constructed in a classic "I" shape that was the standard of the game. These courts were called tlachtli or tlachco, and the game itself went by the name of ullamaliztli. Not only were these courts and the game used for the thrill of sport but also held significant religious value as well. Typically, when Aztecs resided in a new settlement construction of a shrine to Huizilopochtli and a ball court directly next to it was among the first things built. Due to the fact that the largest major cities such as
Tenochtitlan were built upon small islands with marsh-like terrain, these settlements only had so much clean drinking water. This led to the construction of Aztec aqueducts used to bring drinking water from freshwater sources and springs to the Aztec settlements. == Building techniques ==
