This historic hilltop fort with old cannons offers a 360-degree view of the island & ocean. Fort Rodney was built in 1778 with an armament of three 24-pounders and two eleven and a half inch mortars. The cannons sat on timbers on the cobblestone platform, and the platform also served as a water catchment as you can see by the little drain around the walls that runs into the well. Water was used on the gun platform to swab the hot cannons and to remove gunpowder that did not ignite. For drinking, the water was filtered through a 3-gallon limestone filter. Next to the well you can see the powder magazine, a cool underground chamber where the gunpowder was kept.
