Final answer:
The Pyramid of the Feathered Serpent, located in the Ciudadela of the ancient city of Teotihuacan, is an example of talud-tablero architecture and served as a significant religious and political center.
Step-by-step explanation:
Teotihuacan, reaching its zenith from the 1st century to the mid-6th century CE, was a Mesoamerican city known for its magnificent architectural structures such as the Pyramid of the Sun, the Pyramid of the Moon, and the Avenue of the Dead. One of the city's most significant religious and political centers was the Ciudadela, which housed the Pyramid of the Feathered Serpent (Quetzalcoatl). The pyramid was a seven-tiered structure that showcased the Teotihuacan architectural style, particularly its talud-tablero construction. The site also contained sophisticated artistic representations of deities, including the Feathered Serpent and the Rain God. The construction of Teotihuacan's ceremonial structures and the Temple of Quetzalcoatl's significance represent the religious and cultural prominence of the city in ancient Mesoamerica.
