The Alnwick Garden is a complex of formal gardens adjacent to Alnwick Castle in the town of Alnwick, Northumberland, England. The gardens have a long history under the Dukes of Northumberland, but fell into disrepair; they have only been revived over the past ten years, and now feature many different themes and influences, built around a central water cascade. The final phase of development is still to come, which will include more gardens and an adventure play area.
