A terrace and woodland garden set in the hills of Snowdonia. Edward Milner helped with the design, establishing a link with Joseph Paxton and JC Loudon. Tree planting began in the 'picturesque' 1790s. The first Lord Aberconway's father-in-law bought the estate in 1875, started the Dell garden and planted the laburnum tunnel - a famous sight in June. His grandson took charge of the estate in 1901, designed the terraced garden and became a keen plantsman. Clearly, he was inspired by the Arts and Crafts movement. The second Lord Aberconway also started the collection of rhododendrons and magnolias, suscribed to plant-collecting expeditions, grew the seed and passed the enthusiasm to his son, the third Lord Aberconway. A Pin Mill was imported from the Cotswolds in 1938, for use as a garden pavilion on the Canal Terrace.
