Alfred's Castle

Ashdown House (also known as Ashdown Park) is a 17th-century country house in the civil parish of Ashbury in the English county of Oxfordshire. Until 1974 the house was in the county of Berkshire, and the nearby village of Lambourn remains in that county. It is a Grade I listed building and the grounds are included in the Register of Historic Parks and Gardens at Grade II*.

Ashdown Park is a 9.3-hectare (23-acre) biological Site of Special Scientific Interest (SSSI) south of Ashbury in Oxfordshire. The SSSI is part of the park of Ashdown House. The park has been designated an SSSI because of the lichens on its many sarsen boulders. These are in parkland which is heavily grazed to ensure that the lichens, which have taken centuries to grow, do not become shaded. Noteworthy species include Aspicilia caesiocinerea, Buellia saxorum, Candelariella coralliza, Rinodina atrocinerea and Parmelia loxodes.The park is owned by the National Trust and is open to the public.

Wayland's Smithy is an Early Neolithic chambered long barrow located near the village of Ashbury in the south-central English county of Oxfordshire. The barrow is believed to have been constructed about 3600 BC by pastoral communities shortly after the introduction of agriculture to the British Isles from continental Europe. Although part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, Wayland's Smithy belongs to a localised regional variant of barrows - found only in south-west of Britain - known as the Severn-Cotswold group. Wayland's Smithy is one of the best surviving examples of this type of barrow. The site's appearance is a result of restoration following excavations undertaken by archaeologists, Stuart Piggott and Richard Atkinson, in 1962–63. Their research of the site showed it had been built in two different phases. First as a timber-chambered oval barrow built around 3590 and 3550 BC and then later as a stone-chambered long barrow in around 3460 to 3400 BC. The barrow is on the same hill range as Uffington White Horse and Uffington Castle; it is also close to The Ridgeway, the ancient trackway across the Berkshire Downs. The barrow, which is a scheduled monument, is under the guardianship of English Heritage and open all year round. It has been used as a ritual site in modern Paganism since the late 20th century.
