Saint-Helier, a market town, seaport, and the capital of the island of Jersey in the English channel, on the S. coast; pop. in 1871, 30,756. It is situated at the base of an amphitheatre of low hills sloping to St. Aubin's bay. The Victoria and Albert piers enclose a spacious harbor defended by Fort Regent and Castle Elizabeth. Near Castle rock is the hermitage said to have been the retreat of St. Hélier, from whom the town takes its name. There are several main thoroughfares intersected by narrow and irregular streets, but well paved and drained and lighted with gas. The principal buildings are the court house built in 1647, in which is the public library founded in 1736, and the college erected in commemoration of the queen's visit in 1846. There are seven parish churches, St. Hélier's dating from 1341, 14 other places of worship for different denominations, several schools and benevolent institutions, six banks, a theatre, and a market house. Ship building is an important industry, and there are several founderies and breweries. The coasting trade in oysters and fish is extensive, and the fisheries and Newfoundland trade employ about 10,000 tons of shipping and 1,500 hands.

The mild climate and cheap living make the place a favorite resort.
