Sr., the capital of Jersey; N. Lat. 49.11, W. Long. 2.6. It is situated on St Aubin's Bay, on the S. coast of the island, between two rocky headlands, on one of which stands Fort Regent, an irregular fort of great strength, erected in 1806, at a cost of £800,000. The fortress of Elizabeth Castle, capable of containing 600 men, stands on a small rocky island, which, though about a mile from the shore, is accessible at low water by a long natural causeway. The port is large, and consists of an inner and an outer harbour, the latter completed in 1846. The town of St Helier is rapidly extending; and in the outskirts there are many handsome villas. The court-house in the Royal Square is a plain structure erected in 1647. In it the "states assembly" hold their meetings. The parish church was built in 1841. The theatre is a neat building, with a light piazza. St Helier has a public library and reading-rooms, baths, savings bank, hospital, and several other benevolent institutions. Shipbuilding is extensively carried on. The cheapness of living has induced many persons of limited means to settle here. Pop. (1851) 29,133.
