The La Ceiba water tank is a piece of public infrastructure that acquired an unexpected cultural dimension. The tank is decorated with imagery of the ceiba tree — the sacred World Tree of Maya cosmology — in a style that blends Art Nouveau decorative sensibility with pre-Columbian symbolism. It's an oddity in the best sense: a mundane water tower turned into a cultural statement.
Atlas Obscura notes this as a quirky landmark, and it does have a certain appeal as an example of Mexico's 20th-century project of incorporating indigenous imagery into public life. It's a minor sight, but worth a look if you're already in the area.
