Hoorn, a seaport in the province of North Holland, Holland, on a bay of the Zuider Zee called the Hoornerhop, and a junction station 23½ m. by rail N. by E. of Amsterdam, on the railway to Enkhuizen, with which it is also connected by steam tramway. Pop. (1900) 10,647. Hoorn is distinguished by its old-world air and the beauty and interest of its numerous gabled houses of the 16th and 17th centuries. Many of these are decorated with inscriptions and bas-reliefs, some of which commemorate the battle on the Zuider Zee in 1573, in which the Beggars defeated the Spaniards under Count Bossu. Walks and gardens now surround the town in the place of the old city walls, but a few towers and gateways adorned with various old coats of arms are still standing. The fine Gothic bastion tower overlooking the harbour was built in 1532; the East gate not later than 1578. Among the public buildings of special interest are the picturesque St John’s hospital (1563), now used for military purposes; the old mint; the hospital for aged men and women (beginning of 17th century); the weigh-house (1609); the town hall, in which the states of West Friesland formerly met; and the old court-house, which dates from the beginning of the 17th century, though parts of it are older, containing a modern museum and some early portraits. There are also various charitable and educational institutions, Protestant and Roman Catholic churches and a synagogue. The extensive foreign commerce which Hoorn carried on in the 16th and 17th centuries has almost entirely vanished, but there is still a considerable trade with other parts of the Netherlands, especially in cheese and cattle. The chief industries include gold and silver work, and there are also tobacco factories, saw-mills and some small boat-building yards, a considerable number of vessels being engaged in the Zuider Zee fisheries.
Hoorn, latinized as Horna or Hornum, has existed at least from the first part of the 14th century, as it is mentioned in a document of the year 1311, five years earlier than the date usually assigned for its foundation. In 1356 it received municipal privileges from Count William V. of Holland, and in 1426 it was surrounded with walls. It was at Hoorn in 1416 that the first great net was made for the herring fishery, an industry which long proved an abundant source of wealth to the town. During the 15th century Hoorn shared in the troubles occasioned by the different contending factions; in 1569 the Spanish forces entered the town; but in 1572 it cast in its lot with the states of the Netherlands. In the 16th century it was a commercial centre, important for its trade, fisheries and breweries. A company of commerce and navigation was formed at Hoorn in 1720, and the admiralty offices and storehouses remained here until their removal to Medemblik in 1795. The English under Sir Ralph Abercromby took possession of the town in 1799, and in 1811 it suffered severely from the French. Among the celebrities of Hoorn are William Schouten, who discovered in 1616 the passage round Cape Horn, or Hoorn, as he named it in honour of his birthplace; Abel Janszoon Tasman, whose fame is associated with Tasmania; and Jan Pietersz Coen, governor-general of the Dutch East Indies.
