The Plaza Sotomayor is a plaza in Valparaíso, Chile. It is named after Rafael Sotomayor. The square is lined by buildings occupying full block-fronts of the streets that flank it. The focus of the square is the monument that honors the Chilean sailors who fell during the Battle of Iquique and the Battle of Punta Gruesa. The plaza and surrounding buildings was designated a Zona Típica (historic district) on January 23, 1979.
At the northeastern side of the square are two similar towers, which create a sort of gate entrance to the port from the city. On the opposite side is the building that housed the Intendencia de Valparaíso, which currently is home to the headquarters of the Chilean Navy. The building used by the CSAV and the building that houses the National Council of Culture and the Arts also face the plaza.
Close to the station is the western terminus station of the Valparaíso Metro, that replaced the old railway station.
