To the south of the Toluca Valley, this was successively a civic and religious center, a walled city and a military garrison (650-1550 AD). A jaguar is sculpted in bas-relief on a monolith in the impressive Plaza of the Jaguar. There are also other stone reliefs.

Possibly inhabited by immigrants from Teotihuacan, this architectural complex is made up of clusters of very simple rooms.

This site is unique in Mesoamerica, as it was carved in one piece out of an enormous rock on the edge of a cliff for military initiation purposes. The site was created by the Mexica not long before the Spanish conquest, and is dedicated to the initiation of Eagle and Jaguar-Ocelot warriors. It contains splendid sculptures of these symbols.

This is a small settlement that was subjugated by the Acolhua. It maintains a westward-facing pyramid, which is unusual for Mesoamerica and leads us to suppose that it was dedicated to Huitzilopochtli. There are rooms next to the pyramid in which the rulers lived.

Here lie the ruins of the great city of Texcoco, capital of Acolhuacan (660 to 1521), where once stood the poet king Nezahualcóyotl's palace. Nowadays, only a small architectural complex remains, which allows us to admire the skill of its inhabitants at cutting and maneuvering enormous blocks of stone.

Situated near Texcoco, this pre-Hispanic city was one of the most important settlements of Acolhuacan. It covered an enormous area, extending beyond the boundary marked by a great wall 765 yards long by 23 feet high.

This important Otomi settlement was built in the upper part of the plateau of San Miguel which was a perfect site for monitoring movements in the valley of Acambay, or Los Espejos, in the State of Mexico.

A place of great beauty, popularly known as “Nezahualcoyotl’s Baths” (1421-1521 AD). Designed by the famous poet king of Texcoco, it is said he came here to fast and meditate.  Remarkable for its water works (aqueducts, pools and canals).

Previously known as Old Ixtapaluca, this important ceremonial center in the Valley of Mexico is mentioned in the Xolotl Codex.

This late-eighteenth-century retreat for the pulque magnates of Tlalnepantla now displays Mexica stone sculptures and pottery depicting nature, men and the gods, all within the setting of a stately residence.
