Monument to the Revolution: This mural is a stone mosaic representing liberty, symbolized by a naked man with arms raised and looking towards the sky. The figure, known by locals as ‘’El Chulón” (The naked man) is a city landmark and reference spot. The stones forming the mosaic are naturally colored and were collected from different areas of the country. The work for this impressive monument was directed by Mexican artist Claudio Cevallos in joint creation with Salvadoran artist Violeta Bonilla (1921-1999).

Allegory to the 1950 Constitution-or Freedom Monument: The monumental sculpture, a direct stone carving, features a set of nine figures:  a worker, a mother embracing a child, a girl, and two women, one of them partially covered by a soldier holding his rifle peacefully by having it pointing towards the floor. On the back of the sculpture stands another figure of a woman with the Constitution of 1950 in her hands. All together, the figures hold a naked woman covered with the Salvadoran flag that crowns the sculpture. The art piece, created in 1956, by Francisco Zúñiga (1912-1998), a Costa Rican artist (nationalized Mexican) who is considered one of the most important Latin American sculptors with works showcased in several museums and cities around the world.
