The Royal Horticultural Society (RHS) is thrilled to announce the launch of The Harrogate Arms Café, a brand-new venture bringing together Harrogate history, the beautiful landscapes of RHS Garden Harlow Carr and freshly-picked ingredients for a unique plot-to-plate experience.br Originally built in 1844 by then-owner of the estate Henry Wright, the Harrogate Arms and the nearby Bath House were set in pleasure gardens which are now part of RHS Garden Harlow Carr.
