Republic of the Children, Theme park and national monument in Manuel B. Gonnet, Argentina.

The Republic of the Children is a 53-hectare park in Manuel Bernardo Gonnet with 35 scale buildings, including a legislature modelled on the British Parliament, a bank copied from the Doge's Palace in Venice, and a Palace of Culture inspired by the Taj Mahal. A 2 km narrow-gauge railway with five stations, first served by a Decauville locomotive, circles the grounds.

The park opened in 1951 on former golf club grounds during the presidency of Juan Domingo Perón and served as an educational facility for children. It is considered the first theme park in the Americas and later received national monument status.

Since 1986, the program "Los Niños Gobiernan la República" has local students act as deputies and senators and draft "Declaraciones Infantiles". Each November 26, the La Plata Deliberative Council holds a special session on these declarations; approved ones become binding rules across the district. A braille edition, "El Camino de la Ley", made with Escuela 515 de Gonnet, placed braille plaques on every bench of the Government House.

Information about opening hours and admission can be found on the official website or by contacting the park administration by phone. The park is located in Manuel Bernardo Gonnet near La Plata and is accessible by car or public transport.

The claim that Walt Disney drew inspiration from the park for Disneyland is an urban myth, not a documented fact. A more concrete detail: the park's 2 km narrow-gauge railway, with five stations, used a first locomotive built by the French firm Decauville.
