Near the top of the Queen's Staircase at the highest point of the island stand the ruins of Fort Fincastle, built by Governor Lord Dunmore in 1793. Although small and never tested in battle, the fort provided an excellent vantage point for the lookouts posted to give warning of approaching pirates. Those panoramic views of the island, the harbor and surrounding waters are prized today by both tourists and locals. The fort's name honors Lord Dunmore's second title, Viscount Fincastle. The adjacent 126 foot water tower was built in the early 1900s and has also served as a lighthouse. The observation deck provides outstanding views of the area, offering true value for the minimal admission charge.
