Memorial Tres Sillas, Memorial site in Renca, Chile.

Memorial Tres Sillas features three towering steel chairs positioned along Vespucio Norte avenue in Renca. The structure rises approximately 10 meters and creates a distinctive silhouette against Santiago's skyline.

The memorial honors Santiago Nattino, José Manuel Parada, and Manuel Guerrero, three educators killed by military regime agents in March 1985. It was built to preserve their memory and their resistance to oppression.

The three giant chairs copy the design of school chairs, recalling both the victims' work in education and their abduction at the gates of the Colegio Latinoamericano. A concrete walkway with engraved plaques leads to the Plaza del Encuentro, the wooded spot where the bodies were found.

The site is located along Vespucio Norte avenue at kilometer 18 and is easily accessible by car with parking spaces and pedestrian entry points available. Visiting during daylight hours is recommended for safety and better visibility of the memorial.

The giant steel chairs are visible from aircraft approaching Santiago's airport, offering an unusual aerial perspective of the monument. This visibility from above makes the memorial a distinctive landmark that travelers often notice during flights.
