William George Armstrong (later Lord Armstrong) the armament manufacturer, acquired at various times the land which now forms Jesmond Dene. He enclosed the land and planted it with exotic trees and shrubs, laid paths and built bridges. Lord Armstrong used the Dene as his own private parkland but allowed access to it by the public twice weekly, on payment of a small entrance fee which went to the local hospital.
In 1883 Lord Armstrong presented the main area of Jesmond Dene to the Corporation of Newcastle upon Tyne for the benefit of its citizens and in 1884, the park was formally opened by the Prince and Princess of Wales. To commemorate the occasion, the Princess planted a turkey Oak near the Banqueting Hall. This tree, now mature, can still be seen adjacent to the South end of the Banqueting Hall, near to a second tree planted by Alderman H Benson in 1933 to mark the 50th anniversary of the occasion. Since then, the Dene has remained a popular resort for the citizens of Newcastle and, despite heavy pressures put upon it, still retains a particular charm of its own.
