Built more than a thousand years ago, this Norman castle was remodeled extensively during the Middle Ages and in 1600 was surrounded by a mile of artillery fortifications to defend against the threat of the Spanish Armada. During the English Civil War, Carisbrooke served as a prison for Royalists, most notably King Charles I, who tried (unsuccessfully) to escape through a still-visible, tiny window in the north curtain wall. (The small museum has memorabilia relating to the imprisoned king.) The castle was restored during Victoria's reign and served as the residence of her daughter, Princess Beatrice, memorialized in a namesake Edwardian-style garden here. There are excellent views from the top of the Norman keep and battlements. Children love meeting the donkeys who still pull the wheel that draws water from the castle well, along with the medieval joust re-creations in August. The castle is about a mile southwest of the Isle of Wight's capital, Newport, and 5 miles from Cowes. From Cowes, take Bus 1 or 5 (1 from West Cowes, near Holmwood Hotel; 5 from East Cowes, near Osborne House) to Newport Bus Station, then change to Bus 7, which takes you to Carisbrooke High Street, a seven-minute walk from the castle.
