While the large moat and 79 cannons once served to protect India’s Portuguese colonies, Fort Aguada, named after the freshwater springs within its walls, also replenished water supplies of passing ships. The four-story Fort Aguada Lighthouse, built in 1864, is the oldest lighthouse of its kind anywhere in Asia.
The fort sits just over 2 miles (3.2 kilometers) south of Sinquerim Beach, and much of the walk is uphill. Unless you plan to take a taxi or bus, get an early start to tour the fort before the sun beating down on the bare stones makes things too hot for comfort. The fort has few shaded areas, so bring plenty of sunscreen and water with you.
