Edificio de El Mercurio de Valparaíso, Newspaper building in Valparaíso, Chile.

The Edificio de El Mercurio de Valparaíso stands at the corner of Esmeralda Street and Concepción rise in Valparaíso, Chile. Built from 1899 to a design by engineers Augusto Geiger and Carlos Barroilhet, it opened on 5 April 1901. Its historicist facades are eclectic, and the figure of the god Mercury, one arm raised toward the sky, dominates the exterior.

Construction began in 1899 under engineers Augusto Geiger and Carlos Barroilhet, and the building opened on 5 April 1901. It was the first structure designed specifically to house a newspaper's printing presses and editorial offices. In 1979 a renovation by Christian de Groote, Hugo Molina, Gloria Barros and Jacqueline Pertuiset removed interior wall coverings, exposing the masonry across some 5,000 m².

The facade carries a statue of the god Mercury, arm raised toward the sky, a fitting figure for a newspaper building. The paper takes its name from the messenger of the gods, and the sculpture marks the corner where Esmeralda meets the Concepción climb.

The building stands at the corner of Esmeralda Street and Subida Concepción, within the Pasaje Ross Typical Zone. The site slopes steeply, so approach on foot from the lower streets of the plan or climb the stairways and lanes of the hill. The facade and the Mercury statue are visible from the public street.

In 1979 the building received a remodeling award after extensive interior renovations uncovered original brickwork beneath later additions. These restoration efforts revealed the authentic construction methods used when the structure was first built.
