gragoatá
is a neighborhood of rio's sister city,
niterói, which is located just beyond rio de janeiro's
city limits. gragoatá is situated in the city's southern zone, on
the coast of baía guanabara (guanabara bay).
for that reason, it was an excellent strategic location to build a fort.
the forte do gragoatá was built
on the ponta do gragoatá (gragoatá point), a spit of land
offering an excellent view of the
entrance to the bay.
