Tlachtemalácatl (Mesoamerican Ballgame Stone Ring) in Mexico City, Mexico

Coyoacán was once a town completely separate from Mexico City. As such, it needed its own central square, what is now the Plaza Hidalgo. When this plaza was being built, a large stone ring with a figure carved on it was unearthed. This was a tlachtemalácatl, the name in Náhuatl (the language of the Aztec/Mexica people) for the “goals” of the Mesoamerican Ballgame. Known as tlachtli, variants of this game were played by the Indigenous peoples of most of Mexico and Central America, almost always with ritualistic and symbolic purposes.

This particular malacatl of the tlachtli game was so well-carved that it was kept after being found, and eventually placed in a prominent position in the Jesús Reyes Heroles House of Culture, in what is now the Mexico City borough of Coyoacán. This cultural center was once an actual house, and its late 18th-century architecture shows it. It also functioned as a paper factory for some time, and in 1985, was established as a House of Culture.

Its namesake, Jesús Reyes Heroles, was a significant 20th-century intellectual who delved into law, politics, and history. Usually advocating in favor of democratic values and human rights, his legacy led to many institutions other than this center being named after him.
