This water tower, disguised as a castle gate, provided water for the walled garden at Alnwick Castle until at least 1928. It is one of many historic structures in the disused and neglected walled garden that we recorded and reported on as part of the Duchess of Northumberland's innovative Alnwick Garden project. Our work included archival research and condition reports, and also covered the original conservatory, ornamental pool, peach houses and the vineries (below, left), as well as the historic garden walls and the important Gothick style boiler house constructed for the first Duchess around 1765. The new Alnwick Garden, where some of these structures can still be seen, is once again a vibrant, living site and one of the North of England's most popular visitor attractions. We have been privileged to continue our involvement in this important heritage regeneration project by carrying out a full disability access audit to inform further improvements.
