Marle Hall (also Marl Hall) is a Grade II listed Georgian building in Conwy County Borough, North Wales, situated close to Llandudno Junction and Snowdonia National Park. Built by Sir Hugh Williams, 5th Baronet, Marle Hall later became a convalescent home, and in 1971 was bought by Warwickshire County Council, who used it as an educational outward-bound centre that schools in the county could hire. Warwickshire County Council sold the property in March 2022, citing the high maintenance cost, its under use, and the large amount of work required to modernise the building.
