Elizabeth Castle is a 16th-century fortress situated on the tidal island of St Aubin's Bay in Jersey. The site remains accessible only by sea or a man-made causeway depending on the state of the tide. It was established by Sir Walter Raleigh, who served as Governor of Jersey from 1600 to 1603. The structure replaced the medieval Mont Orgueil as the island's primary defensive fortification. During the English Civil War, the castle served as a refuge for the future King Charles II. It features a range of defensive structures, including bunkers, barracks, and magazine stores from various military eras. The site is currently managed by Jersey Heritage and functions as an open-air museum detailing over 400 years of military history. Visitors encounter a mix of Cromwellian and Victorian military architecture across the rocky islet. Its strategic location protected the port of St Helier against French naval incursions for centuries.
