Fort Copacabana
In 1922, the fort's own guns opened fire on Rio — then the Brazilian navy shot back.

Built between 1908 and 1914 to guard Copacabana beach and Rio's harbor entrance, this headland fort became the flashpoint for Brazil's first tenentista revolt. Today the base is open to the public and houses the Museu Histórico do Exército (Army Historical Museum), with the original armored cupolas still in place.
What to look for
- The "Duque de Caxias" cupola housing two 305mm Krupp cannons — each shell weighed 445kg and could reach 23km out to sea
- The lower "André Vidal" cupola with its 190mm Krupp guns, positioned so the heavier battery above could fire clean over it
- The empty flanking casements where 75mm quick-firing guns once sat — removed when Brazil disbanded its coastal artillery branch in 1987
The base sits at the south end of Copacabana beach and is open to the public; the Army Historical Museum is inside the fort.
