history enthusiasts are encouraged to stop by rio's museu histórico do exército e forte de copacabana (museum of army history and forte copacabana) for a well-worth visit - the museum is a wonderful stop on any travel itinerary.

the fortification of the shores of metropolitan rio de janeiro started in 1763, when rio de janeiro  became the capital of brazil. however, the military installation in copacabana only became operational in 1823.

it was part of the measures to defend the city from any retaliatory attacks by the portuguese armada, as a result of brazil seeking independence from portugal. the south-eastern tip of copacabana was the perfect strategic site for the purpose.
