The largest cathedral in the American continent. Designed by Claudio de Arcinieaga, construction started in 1537 and lasted for 250 years. Be sure to check out the side chapels where parishioners leave offerings for the various saints. For a bird's-eye view of the plaza, you can take a 40-minute tour (Spanish language only) of the upper levels and bell towers of the cathedral (M$12).
The Metropolitan Cathedral of the Assumption of the Most Blessed Virgin Mary into Heaven, also commonly called the Mexico City Metropolitan Cathedral, is the cathedral church of the Catholic Archdiocese of Mexico. It is situated on top of the former Aztec sacred precinct near the Templo Mayor on the northern side of the Plaza de la Constitución (Zócalo) in the historic center of Mexico City. The cathedral was built in sections from 1573 to 1813 around the original church that was constructed soon after the Spanish conquest of Tenochtitlan, eventually replacing it entirely. Spanish architect Claudio de Arciniega planned the construction, drawing inspiration from Gothic cathedrals in Spain.

Housed in the historic 16th-century Casa de las Ajaracas, it is a rare survivor on a street that has seen other historic structures knocked down to explore the Templo Mayor site. The museum is home to a huge collection of historical photographs from the 19th, 20th and 21st centuries, documenting the constantly changing cityscape of Mexico City.
This building, which was completed in 1758, was built on the grounds of the house of Aztec emperor Moctezuma and later the residence of the Spanish conqueror Hernán Cortés. The building was acquired in 1838 by the Nacional Monte de Piedad, a pawn shop established in 1775 that still operates today.
