Ilha de Mocanguê, Naval base island in Guanabara Bay, Brazil
Ilha de Mocanguê is a military island in Guanabara Bay that houses several naval facilities and marine training centers for personnel development. The island was created by filling the channel between two original landmasses to form one consolidated base for naval operations.
Until 1973 the Lloyd Brasileiro Navigation Company operated a shipyard here before the Brazilian Navy took over the site. The conversion to a naval base marked a turning point in the industrial use of the location.
The Brazilian Navy maintains multiple military organizations on the island dedicated to personnel training and maritime operations development.
Access to the island requires authorization from the Brazilian Navy since it operates as an active military facility. Visitors should check with the naval authorities in advance to learn whether a visit is possible.
The channel between the two original islands was filled to create one consolidated landmass for the Rio de Janeiro Naval Base.
