(Nahuatl: "place among the reeds"; Spanish "carrizal") is an archeological zone of the early Aztec (or early Toltec) culture located in the town of Santa Cecilia, in the municipality of Tlalnepantla de Baz in the State of Mexico, about 10 km northwest of Mexico City.

Along with Tenayuca, it was later annexed by the Mexica and became part of the lacustrine culture of the Valley of Mexico under the rule of Tenochtitlan, until the arrival of the conquistadors in 1521.

The exterior structures were removed and many of their stones were used to build the adjacent church, which dates back to the late 16th century.

In 1962, the architect and archaeologist Eduardo Pareyon Moreno reconstructed and reinforced the pyramid's basement and rebuilt the temple that crowns it.

Although such a reconstruction certainly does not comply with current canons of archaeology, the product is a beautifully delineated Mexica pyramid, one of the best-conserved examples of this culture.
