Elizabeth Castle

Elizabeth Castle is a fortified complex on a tidal islet in St Aubin’s Bay, off St Helier in Jersey, Channel Islands. It dates to the late 16th century and takes its name from Queen Elizabeth I.

The site preserves multiple defensive structures including batteries, barracks and a central keep, and it functions today as a historic attraction with displays about the island’s military past. Visitors commonly use the seasonal ferry service or cross the tidal causeway at low water to reach the castle.

Elizabeth Castle was developed to control the approaches to St Helier and to replace earlier medieval fortifications on the islet; it was used and upgraded over several centuries for coastal defence. Its buildings show layers of work from the Elizabethan period through later centuries.

Sited on a low rocky islet in St Aubin’s Bay, the castle sits a short distance offshore from central St Helier and commands views across the bay. Tidal conditions determine pedestrian access, so crossing times vary by day.

• Access: Accessible on foot at low tide via a causeway or year-round by small passenger ferry from St Helier, depending on the tide.
• What to expect: Contains fortified walls, barracks and gun batteries that illustrate its role in coastal defence from the 16th century onward.
