Park Farm Down

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.

Fognam Chalk Quarry is a 3-hectare (7.4-acre) geological Site of Special Scientific Interest west of Upper Lambourn in Berkshire. It is a Geological Conservation Review site. It is in the North Wessex Downs.The site is private land with no public access.

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*.

Alfred's Castle is a small Iron Age hill fort, situated at grid reference SU277822, behind Ashdown Park in the civil parish of Ashbury in Oxfordshire (formerly Berkshire). It lies 2–3 km south of the Ridgeway and is protected as a Scheduled Ancient Monument.It has a large enclosure attached that shows as a cropmark. Excavation has shown this to be contemporary with the small enclosure, started in the 6th century BC. The hill fort was established within a series of late Bronze Age linear ditches and revealed much evidence for occupation within it. In the late 1st century, a Romano-British farmhouse was built within the abandoned prehistoric enclosure. King Alfred won a great victory against the Danes at the Battle of Ashdown, in AD 871. Being located just to the west of Ashdown House, Victorian antiquaries associated Alfred's Castle with the King's troop movements before the battle. The exact site of Alfred's battle has not yet been determined, however, so is a matter for debate. The most likely sites are near Compton and Aldworth in Berkshire. Excavations were carried out at Alfred's Castle from 1998 to 2000 by archaeologists from Oxford University. A final analysis was published in 2014.

Upper Lambourn is a small village in the county of Berkshire, England. The village is situated in the civil parish of Lambourn , and is 1.2 miles (2 km) to the north-west of the village of Lambourn, just off the Lambourn to Shrivenham road. The parish is within the district of West Berkshire, close to the point where the counties of Berkshire, Oxfordshire and Wiltshire meet.

The Berkshire Downs are a range of chalk downland hills in southern England, part of the North Wessex Downs Area of Outstanding Natural Beauty. The Berkshire Downs are wholly within the traditional county of Berkshire, although split between the current ceremonial counties of Berkshire and Oxfordshire. The western parts of the downs are also known as the Lambourn Downs.

Uffington Castle is an early Iron Age (with underlying Bronze Age) univallate hillfort in Oxfordshire, England. It covers about 32,000 square metres and is surrounded by two earth banks separated by a ditch with an entrance in the western end. A second entrance in the eastern end was apparently blocked up a few centuries after it was built. The original defensive ditch was V-shaped with a small box rampart in front and a larger one behind it. Timber posts stood on the ramparts. Later the ditch was deepened and the extra material dumped on top of the ramparts to increase their size. A parapet wall of sarsen stones lined the top of the innermost rampart. It is very close to the Uffington White Horse on White Horse Hill.

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.

The Uffington White Horse is a prehistoric hill figure, 110 m (360 ft) long, formed from deep trenches filled with crushed white chalk. The figure is situated on the upper slopes of Whitehorse Hill in the English civil parish of Uffington in Oxfordshire, some 16 km (10 mi) east of Swindon, 8 km (5.0 mi) south of the town of Faringdon and a similar distance west of the town of Wantage; or 2.5 km (1.6 mi) south of Uffington. The hill forms a part of the scarp of the Berkshire Downs and overlooks the Vale of White Horse to the north. The best views of the figure are obtained from the air, or from directly across the Vale, particularly around the villages of Great Coxwell, Longcot, and Fernham. The Uffington White Horse was created some time between 1380 and 550 BC, during the late Bronze Age or early Iron Age. The site is owned and managed by the National Trust and is a scheduled monument. The Guardian stated in 2003 that "for more than 3,000 years, the Uffington White Horse has been jealously guarded as a masterpiece of minimalist art." The Uffington Horse is by far the oldest of the white horse figures in Britain; the others inspired by it have an entirely different design.

Whitehorse Hill is a hill in the Berkshire Downs in Oxfordshire, England, west of Wantage. At 261 metres (856 ft), it is the highest point in Oxfordshire. Uffington Castle lies on the summit of the hill, and the Uffington White Horse is on the hill's northern slope. The hill and an adjacent area below, including Dragon Hill and The Manger, make up a 98.9-hectare (244-acre) biological and geological Site of Special Scientific Interest.The Manger, a dry valley below the hill, is a Geological Conservation Review site. It provides evidence of solifluction (slow slipping of soil downhill due to repeated freezing and thawing) during at least one cold stage of the Pleistocene. The site has unimproved chalk grassland with a rich variety of flora, particularly in former chalk quarries. Grasses include upright brome and sheep’s fescue.The Ridgeway National Trail crosses the hill south of Uffington Castle.

Croker's Hole is a 4.4-hectare (11-acre) biological Site of Special Scientific Interest north of Upper Lambourn in Berkshire.The site is a narrow grassland valley, which is one of the most florally diverse chalk downlands in Berkshire. The dominant plants are upright brome and tor-grass, and it is the only site in the county which has the nationally scarce bastard toadflax.There is access from a footpath from Seven Barrows to Hangman's Stone.

Dragon Hill is a small hillock immediately below the Uffington White Horse on the border of the civil parishes of Uffington and Woolstone in the English county of Oxfordshire. In 1974 it was transferred from Berkshire. Dragon Hill is a natural chalk hill with an artificially flattened top (on the scarp slope of White Horse Hill); according to legend, Saint George slew the dragon here. A bare patch of chalk upon which no grass will grow is purported to be where the dragon's blood spilled. It has been suggested as some sort of Iron Age ritual site associated with the nearby hill figure.It is part of the White Horse group of monuments in the care of the National Trust, and a Scheduled Monument in its own right.
