Casino Sierra de la Ventana, located in Tornquist municipality in Buenos Aires Province, is associated with a historic resort complex originally opened in 1911 as one of Argentina's pioneering luxury hotel-casinos. While the original Belle Époque building was reduced to ruins by fire in 1983 and declared a provincial historic monument, modern gaming operations have been established in the region. The venue operates within the contemporary casino infrastructure developed by the Provincial Lottery and Casinos Institute, serving the nearby Ernesto Tornquist Provincial Park and mountain tourism area.
