About
Elizabeth Castle stands on a rocky tidal islet in St Aubin's Bay, a little under a mile offshore from St Helier, and is cut off from Jersey by the sea twice a day. Sir Walter Raleigh, Governor of Jersey from 1600, named the fortress for Elizabeth I, and it was begun in the 1590s to replace Mont Orgueil on the island's east coast, whose medieval walls had been made obsolete by artillery. Four centuries of continuous military use followed, and successive garrisons rebuilt and extended the defences until the castle covered its whole rock: the Elizabethan upper ward, an eighteenth-century lower ward, Napoleonic-era batteries and, finally, German concrete added during the occupation of 1940-45.
The castle's central place in Jersey's history comes from the Civil War. The future Charles II sheltered here twice, in 1646 as Prince of Wales and again in 1649 after his father's execution, and it was in Jersey that he was first proclaimed King. Parliamentary forces besieged the castle in 1651; it held out for seven weeks until a mortar shell struck the medieval abbey church at its heart, which was being used as the magazine, and the resulting explosion destroyed both the church and the garrison's stores. The abbey, dedicated to St Helier, had given the town its name.
On a smaller rock beside the castle stands the Hermitage, traditionally the cell of Helier himself, a sixth-century hermit killed by raiders and later adopted as the island's patron saint. Pilgrims have visited the rock for well over a thousand years, and it is reachable on foot at low tide.
Visitors cross either by walking the causeway when the tide allows or by riding the amphibious Castle Ferry, a wheeled vehicle that drives into the sea. Inside, the Jersey Militia Museum, restored barrack interiors, occupation-era bunkers and costumed living-history interpretation fill a site that takes most of a day to see properly, with a noon gun fired in season.

💡 Visitor Tips
- Check the tide table before you go — the causeway is walkable only around low water, and the ferry is the only other way across.
- The amphibious ferry can be suspended in strong wind or heavy swell, so confirm with Jersey Heritage on the day if the weather is rough.
- Allow at least three hours; between the militia museum, the bunkers, the upper ward and the Hermitage there is far more here than a single-castle visit suggests.
- Walk out at low tide and take the ferry back if you can — the causeway approach gives much the better sense of the castle's setting.
- The Hermitage is reachable only at low tide by a rock-cut stair, so plan the visit around it rather than hoping to fit it in.
- Wear proper footwear and a windproof layer; the site is exposed on all sides and much of the walking is on stone ramps and steps.
- The castle is closed on 9-10 September 2026 for the Jersey International Air Display — check dates if visiting in early September.
- If you are seeing several Jersey Heritage sites, ask about a multi-site pass at the ticket desk rather than paying separately at each.
Highlights
The Amphibious Castle Ferry
For most of the day the castle is an island, and the crossing is made in an amphibious vehicle that drives down the slipway at West Park, floats across St Aubin's Bay and climbs out onto the castle causeway at the far end. Children in particular treat the ferry as the main event of the day, and it is genuinely unusual — few British heritage sites are reached by a vehicle that swims.
Services run through the day in season but can be suspended in strong wind or heavy swell, so it is worth checking conditions before setting out from St Helier.
The Hermitage of St Helier
On a smaller rock beside the castle stands a small stone oratory built over the cell traditionally occupied by Helier, a sixth-century hermit who lived on the rock and was killed by seaborne raiders in about 555. He became the island's patron saint and gave his name to its capital. Pilgrims have come to the rock for well over a thousand years, and a pilgrimage is still made annually.
The Hermitage is reached on foot at low tide by a rock-cut stair from the castle, and it is the oldest thing on the site by a margin of a thousand years.
Charles II in Exile
The future Charles II sheltered at Elizabeth Castle twice: in 1646 as Prince of Wales, fleeing the collapse of the Royalist cause in England, and again in 1649 after his father's execution, when Jersey became one of the first places in his dominions to proclaim him King. Sir George Carteret, the island's Royalist Lieutenant Governor, held Jersey for the Crown throughout, and the Carolina colony in North America was later named in the King's honour with Carteret among its proprietors — the connection that also gave New Jersey its name.
The castle's interpretation covers this period in detail.
The 1651 Siege and the Destruction of the Abbey
Parliamentary forces landed in Jersey in October 1651 and besieged Elizabeth Castle, which held out for seven weeks under Sir George Carteret. The siege ended when a mortar shell struck the medieval abbey church of St Helier at the castle's heart, which the garrison was using as its magazine; the explosion destroyed the church, the stores and the garrison's ability to continue.
Carteret surrendered in December on honourable terms.
The abbey was never rebuilt, and its loss is the reason the centre of the castle is an open parade ground rather than a standing medieval church.
Collections
Elizabeth Castle is a fortification of the 1590s to the 1940s occupying a tidal islet in St Aubin's Bay, together with the Hermitage of St Helier on the adjoining rock. Displays interpret the castle's construction under Sir Walter Raleigh's governorship, the sheltering of the future Charles II in 1646 and 1649-50, the Parliamentary siege of 1651 that destroyed the medieval abbey church of St Helier, and the German occupation of 1940-45.
The Jersey Militia Museum within the castle covers one of the oldest militia forces in the British Isles through uniforms, weapons, colours and documents.
Restored barrack interiors, Napoleonic batteries and occupation-era bunkers are open to explore, and Jersey Heritage runs costumed living-history interpretation and a noon gun through the season.
