Ilha das Cobras, Naval facility island in Rio de Janeiro Bay, Brazil.
The island extends across 92 acres with its highest point reaching 26 meters, featuring multiple naval structures and a deep-water port.
The Portuguese constructed military fortifications on the island in 1713, establishing it as a crucial defense point for Rio de Janeiro's harbor.
The Brazilian Navy maintains educational facilities on the island, including training centers and specialized maritime instruction programs for military personnel.
Access to Ilha das Cobras requires official authorization from the Brazilian Navy, with security checkpoints monitoring all entry points.
