Origin and name
The square sits on the coastal flat of the bay, facing Muelle Prat, and took shape as the main civic space of the port. In the late 19th century it adopted the name of Rafael Sotomayor Baeza, Minister of War and Navy during the War of the Pacific, tying the place to the country's naval memory.
The end opposite the sea is presided over by the former Intendencia, today the headquarters of the Armada de Chile. The building, designed by Ernesto Urquieta, was completed in 1910 and closes the square with its monumental façade.
The Monumento a los Héroes de Iquique

In 1886 the Monumento a los Héroes de Iquique was inaugurated at the center of the plaza, erected to honor the sailors who fell in the naval battles of Iquique and Punta Gruesa. Over the years it became the most recognizable urban landmark of Valparaíso and a site of institutional ceremonies. A crypt linked to that memory lies beneath the ensemble.
Chile Travel places “1879” beside the monument name; the National Monuments Council dates its erection to 1886. This guide uses 1886 for the monument rather than treating the tourism page’s parenthesis as its inauguration date. CMN · Chile Travel
Heritage recognition
In 1979 Plaza Sotomayor was declared a Zona Típica (Heritage Zone) together with the buildings that enclose it, later extending its protected area toward the pier. In 2003, the historic port area of Valparaíso entered the UNESCO World Heritage List, and the plaza is part of that ensemble.
Between the monument, the former Intendencia and Muelle Prat, the plaza sums up the city's identity: maritime memory, monumental architecture, transport and daily life facing the bay.
