Antigua and Barbuda
See Nelson's Dockyard from a Whole New VantageEnglish Harbour is one of Antigua's crown jewels, so it should be no surprise that Fort Berkeley was erected to protect this excellent protected bay. Placed on the peninsula on the western entrance, this fort has been enforcing entry to the anchorage for nearly 300 years.
Today, the fort is mostly ruins, but it still supplies visitors with stunning views of the harbor. From Nelson's Dockyard it's a fairly short 10-minute stroll to the ramparts and well worth the walk. From here you can see the dockyard's waterfront, every boat that enters the bay, and beautiful Galleon Beach on the opposite shore.
