La Pilita Mural (Martin Moreno)
Tucked back into a side street near the El Tiradito wishing shrine, this mural is one of Barrio Viejo's greatest gems. It was originally painted in the '80s by students under the supervision of muralist Martin Moreno, but was touched up by the artist in 2011. It depicts a Latino family at Gates Pass, with the Aztec feathered serpent deity Quetzalcoatl looking on.
The mural is painted on the side of the now-closed La Pilita Museum, so there's a nice courtyard and places to sit.
