Sitting atop Bennet's Hill, Fort Fincastle is the smallest of Nassau's three colonial forts but the easiest to reach and offers the best views over the harbour and downtown. Its peculiar paddle-wheel-shaped design is a quirk of Lord Dunmore's taste rather than any tactical genius. The walls are walkable in five minutes; the interior is essentially empty.
The fort is most often visited as a pair with the Queen's Staircase at its foot. Local guides hang around offering history tours; the better ones know their stuff and the worst will hassle you. Admission is a small fee, sometimes waived. Combine with the Water Tower next door, the tallest structure in Nassau, for a 360-degree view of New Providence.
