Mesoamerican architecture is the set of architectural traditions produced by pre-Columbian cultures and civilizations of Mesoamerica, traditions which are best known in the form of public, ceremonial and urban monumental buildings and structures. The distinctive features of Mesoamerican architecture encompass a number of different regional and historical styles, which however are significantly interrelated. These styles developed throughout the different phases of Mesoamerican history as a result of the intensive cultural exchange between the different cultures of the Mesoamerican culture area through thousands of years. Mesoamerican architecture is mostly noted for its pyramids, which are the largest such structures outside of Ancient Egypt. One interesting and widely researched topic is the relation between cosmovision, religion, geography, and architecture in Mesoamerica. Much seems to suggest that many traits of Mesoamerican architecture were governed by religious and mythological ideas. For example, the layout of most Mesoamerican cities seem to be influenced by the cardinal directions and their mythological and symbolic meanings in Mesoamerican culture. Another part of Mesoamerican architecture is its iconography. The monumental architecture of Mesoamerica was decorated with images of religious and cultural significance, and also in many cases with writing in some of the Mesoamerican writing systems. Iconographic decorations and texts on buildings are important contributors to the overall current knowledge of pre-Columbian Mesoamerican society, history and religion.

Symbolism
An important part of the Mesoamerican religious system was replicating their beliefs in concrete tangible forms, in effect making the world an embodiment of their beliefs. This meant that the Mesoamerican city was constructed to be a microcosm, manifesting the same division that existed in the religious, mythical geography—a division between the underworld and the human world. The underworld was represented by the direction north and many structures and buildings related to the underworld, such as tombs, are often found in the city's northern half. The southern part represented life, sustenance, and rebirth and often contained structures related to the continuity and daily function of the city-state, such as monuments depicting the noble lineages, or residential quarters, markets, etc. Between the two halves of the north/south axis was the plaza, often containing stelae resembling the world tree the Mesoamerican axis mundi, and a ballcourt which served as a crossing point between the two worlds. Some Mesoamericanists argue that in religious symbolism the Mesoamerican monumental architecture pyramids were mountains, stelae were trees, and wells, ballcourts and cenotes were caves that provided access to the underworld.
Orientation Mesoamerican architecture is often designed to align to specific celestial events. Some pyramids, temples, and other structures were designed to achieve special lighting effects on particular days important in the Mesoamerican cosmovision. A famous example is the "El Castillo" pyramid at Chichen Itza, where a light-and-shadow effect can be observed during several weeks around the equinoxes. Contrary to a common opinion, however, there is no evidence that this phenomenon was the result of a purposeful design intended to commemorate the equinoxes. Much Mesoamerican architecture is also aligned to roughly 15° east of north. Vincent H Malmstrom has argued that this is because of a general wish to align the pyramids to face the sunset on August 13, which was the beginning date of the Maya Long Count calendar. However, recent research has shown that the earliest orientations marking sunsets on August 13 (and April 30) occur outside of the Maya area. Their purpose must have been to record the dates separated by a period of 260 days (from August 13 to April 30), equivalent to the length of the sacred Mesoamerican calendrical count. In general, the orientations in Mesoamerican architecture tend to mark the dates separated by multiples of 13 and 20 days, i.e. of basic periods of the calendrical system. The distribution of these dates in the year suggests that the orientations allowed the use of observational calendars that facilitated the prediction of agriculturally significant dates. These conclusions are supported by the results of systematic research accomplished in various Mesoamerican regions, including central Mexico, the Maya Lowlands, Oaxaca, the Gulf Coast lowlands, and western and northern Mesoamerica. While solar orientations prevail, some prominent buildings were aligned to Venus extremes, a notable example being the Governor's Palace at Uxmal. Orientations to lunar standstill positions on the horizon have also been documented; they are particularly common along the Northeast Coast of the Yucatán peninsula, where the worship of the goddess Ixchel, associated with the Moon, is known to have had an outstanding importance during the Postclassic period.
The Plaza
Nearly every known ancient Mesoamerican city had one or more formal public plazas. They are typically large impressive spaces, surrounded by tall pyramids, temples, and other important buildings. Activities that would take place in these plazas would include private rituals, periodic markets, mass spectator ceremonies, participatory public ceremonies, feasts, and other popular celebrations. The size of the main plazas in Mesoamerican cities differed greatly, the largest being located in Tenochtitlan with an estimated size of 115,000 square meters. This plaza is an outlier due to the population of the city being so large. The next largest estimated plaza is located in the Gulf Coast in the city of Cempoala (or Zempoala), measuring at 48,088 square meters. Most plazas average at around 3,000 square meters, the smallest being at the site of Paxte which is 528 square meters. Some cities contain many smaller plazas throughout, while some focus their attention on a significantly large main plaza.
