These spaces are named after the communist militant and official of the Municipality of Santiago, Lincoyán Berríos, who was arrested on December 15, 1976 on public roads by agents of the Dirección Nacional de Inteligencia, DINA.
Berríos was President of the Asociación Nacional de Funcionarios Municipales y Dirigente de la Central Latinoamericana de Trabajadores Estatales, among other positions in his vast union career. In 1973 he had been re-elected as President of the Asociación de Empleados Muniicpales, a position from which he was exonerated after the Golpe de Estado. His remains were found in 2001 in the Los Bronces mine in Cuesta Barriga and finally identified in July 2012.
In 2014, the Municipality of Santiago installed a monolith in honor of Lincoyán in the square located in Santo Domingo with 21 de Mayo. And in 2023, the Municipality, in the context of the commemoration activities of the 50 years of the Golpe de Estado in Chile, renamed the space as Plazoleta Lincoyán Berríos and the monolith that commemorates him was moved to the interior patio of the Town Hall Palace of the Municipality of Santiago, which was also renamed Lincoyán Berríos, in his memory.
21 de Mayo, 500, Santiago.
