HORNSEY, a municipal borough in Middlesex, England, 6 m. N. of St. Paul's Cathedral, on the L.N.E.R. Pop. The manor, called in the 13th century Haringee (a name which survives as Harringay), belonged from an early date to the see of London, the bishops having a seat here. In 1387 the duke of Gloucester, uncle of Richard II., assembled in Hornsey Park the forces by the display of which he compelled the king to dismiss his minister de la Pole, earl of Suffolk; and in 1483 the park was the scene of the ceremonious reception of Edward V., under the charge of Richard, duke of Gloucester, by Edmund Shaw, lord mayor of London. The parish church of St. Mary, Hornsey, has a Perpendicular tower (c. 1500). Finsbury Park, of 120 ac., is within the borough. Hornsey was incorporated in 1903.
