Remains of Hernán Cortés' house, which was later used as the Viceroys' Palace, are displayed in the last two archaeological windows of the National Palace.

Beneath the tabernacle of the Metropolitan Cathedral, down a metal staircase located on the north side of the building, there are two windows that reveal three sections of architectural remains corresponding to the north side of the Temple of the Sun or Tonatihu.

A section of the temple of Ehécatl Quetzalcóatl was discovered by the PAU between 2009 and 2010.

Models and sacred structures such as a tree and a Cuauhxicalco are now open to the public thanks to recent discoveries and the ongoing work of the Urban Archaeology Project (PAU).
