Final answer:
The Pyramids of Teotihuacan, including the Pyramid of the Sun, Pyramid of the Moon, and Temple of the Feathered Serpent, are important structures in the ancient city of Teotihuacan.
Step-by-step explanation:
The Pyramid of the Sun and the Pyramid of the Moon are two major structures in Teotihuacan, a pre-Columbian Mesoamerican city in Mexico. The Pyramid of the Sun was built in two phases, with the first phase dating back to 100 CE and the second phase estimated to be around 200 CE. The Pyramid of the Moon is believed to have been built around 250 CE.
Another important structure in Teotihuacan is the Temple of the Feathered Serpent, also known as the Temple of Quetzalcoatl. This temple exhibits the talud-tablero construction style and was enlarged several times, with each enlargement enclosing the previous structure. It is a seven-tiered structure and is a significant example of Teotihuacan architectural style.
