Final answer:
The central architectural feature of the Mayan city of Teotihuacan was the Avenue of the Dead. This passageway was surrounded by major structures such as the Pyramid of the Sun and the Pyramid of the Moon, along with the Temple of the Feathered Serpent within the Citadel.
Step-by-step explanation:
The central architectural feature of the Mayan city of Teotihuacan was the Avenue of the Dead. Teotihuacan is a site with impressive stone structures, chief among them the Pyramid of the Sun and the Pyramid of the Moon. The Avenue of the Dead is a significant north-south passageway that provides access to these pyramids, and it extends over a mile long. Additionally, the Temple of the Feathered Serpent is another prominent structure, located within the Citadel, a large royal residence.
Contrary to what the question may imply, the Temple of the Inscriptions and the royal acropolis are not central features of Teotihuacan but of other Mayan sites such as Palenque. Teotihuacan also features a ceremonial ball court, where the Mesoamerican ballgame was played, a sport that held religious significance and sometimes involved human sacrifice. These architectural elements are symbolic of the strong cultural and religious practices that thrived within the city.
