Governor Dardo Rocha's proposal for the establishment of a new capital for the paramount Province of Buenos Aires, useful to the mollification of the province's Independence-leaning gentry, was quickly approved by the Argentine Congress following the 1880 Federalization of Buenos Aires. Overseeing a furor of construction, Rocha inaugurated the city of La Plata on November 19, 1882, creating the first planned city in South America, and its first with electric lighting.[1]
Construction on the project began in June 1883, and was completed in 1888. The 14,400 m2 (155,000 ft2) building, an eclecticist design based on German Renaissance Revival architecture, features Romanesque interiors, including two courtyards, City Council chambers, and the Salón Dorado ("Gold Room"), a formal reception hall accessed via a grand, marble staircase, set in Slovenian oak floors, and featuring German vitreaux, and a 1.2 ton spider chandelier.[2]
