"Fortaleza Real Felipe and the Callao District Callao has been one of the most important ports in South America since the colonial era. This seaside district of Lima still echoes a rich maritime history, and historically-minded visitors will find much to explore. Be sure to check out the 18th-century Real Felipe Fortress, which was built to defend the area from pirates. The Naval Museum also provides a fascinating look into the region's past. Afterward, take a walk through the La Punta neighborhood, which maintains a timeless, laid-back feeling with its beautiful beach and its bevy of restaurants."
