Edificio Crucero Guevara, Historical monument in Valparaíso, Chile

The Edificio Crucero Guevara is a five-story building at the corner of Errázuriz Avenue and Blanco Street, on land reclaimed from the sea, with a facade monogram read as LG for Luis Guevara. Restored between 2009 and 2010, it reopened on 25 April 2011 as the Centro de Extensión Duoc UC, Edificio Cousiño, with a theater, convention center and exhibition halls.

The building was constructed between 1881 and 1883 by textile entrepreneur Luis Guevara Arias on land reclaimed from the sea during Valparaíso's maritime development period. This location reflects how the city expanded in the 1800s as new neighborhoods were built on recovered land.

The facade monogram reads LG, for owner Luis Guevara, but was long misread as LC and the building wrongly called Luis Cousiño. DUOC still repeated the error, attributing it to Isidora Goyenechea de Cousiño; the correction came from architect Alberto López and heritage researcher Lautaro Triviño. The Cousiño story actually belongs to the 1890 building opposite, later the Edificio Dacal.

The building sits at a prominent corner intersection, making it easy to locate when walking through the city. Since it now operates as an educational facility, some interior areas may have limited public access.

The facade monogram that many read as "L" and "C" actually stands for LG, for Luis Guevara. The confusion led the building to be wrongly called Luis Cousiño, and the error was only corrected by research by architect Alberto López and heritage researcher Lautaro Triviño. DUOC's own website still repeats the Cousiño story, which belongs to the building opposite, built in 1890 by French architect Marcel Dourgnon.
