standing just at the entrance of the niterói harbor, the ilha do caju (caju island) is part of the important naval industrial complex which grew around the northwestern shores of the city.

it is crossed by the important niterói- rio bridge, which links it to each side of the guanabara bay.

close to the caju island are two important centers for the naval industry, not only in niterói, but in all of guanabara bay too.
