His feast day, marked by an annual municipal and ecumenical pilgrimage to the Hermitage, is on 16 July.

The medieval hagiographies of Helier, the patron saint martyred in Jersey and after whom the parish and town are named, suggest a picture of a small fishing village on the dunes between the marshy land behind and the high-water mark.

An Abbey of Saint Helier was founded in 1155 on L'Islet, a tidal island adjacent to the Hermitage.

Closed at the Reformation, the site of the abbey was fortified to create the castle that replaced Mont Orgueil as the island's major fortress.

The La Collette Yacht Basin is the only one of these to provide non-tidal, 24-hour access to the sea and is home to Jersey's commercial fishing fleet.
