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.

Aldbourne ( AWLD-born) is a village and civil parish about 6 miles (10 km) north-east of Marlborough, Wiltshire, England, in a valley on the south slope of the Lambourn Downs – part of the North Wessex Downs Area of Outstanding Natural Beauty. From here an unnamed winterbourne flows south to join the River Kennet 4 miles (6 km) away near Ramsbury. The 2011 Census recorded the parish population as 1,833. The parish includes the hamlets of Upper Upham and Woodsend and part of the hamlet of Preston, which straddles the boundary with Ramsbury. The village of Snap became deserted in the early 20th century.

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.

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.

Membury Camp, or Membury Fort, is the site of an Iron Age hill fort located on the borders of Wiltshire and Berkshire, (the county line divides the site in two, although the majority of the site lies within Wiltshire). The site encompasses 14 hectares, and is situated in the south-western corner of a small plateau. The circular earthworks are completely shrouded in trees and inside the walls it is mostly arable farmland. To the northeast, in the Berkshire segment, the camp is totally wooded by a small copse, Walls Copse, which covers a quarter of the site. To the north and east the adjoining ground is flat, but to the south and west it falls away steeply, providing a natural defence. The camp consists of a single ditch with banks on either side and encloses and area measuring 390m by 490m. A gap in the east with inturning flanks is probably an original entrance though it is mutilated and overgrown. Other gaps in the banks appear to be more modern. A possible hut circle is visible as a cropmark situated at the south end of the hill fort. The east side of the earthwork has been partly destroyed by the construction of a wartime airfield, RAF Membury. The site has not been excavated but a number of prehistoric finds have been found in the vicinity. It is a scheduled ancient monument no. 228970 There have been several collections of pottery found, in 1977, 1980 and 1987 Other significant finds have also included for flint artefacts from the mesolithic era, and flint tools from the neolithic era, prior to the Iron Age.

The Membury transmitting station is a broadcasting and telecommunications facility, situated adjacent to the M4 motorway at the Membury services in the south-west corner of the parish of Lambourn close to the town of Hungerford, in Berkshire. It is owned and operated by Arqiva. It has a 152.4 m (500 ft) high guyed steel lattice mast. It was constructed by the ITA in 1965 to bring ITV signals (provided by ATV and ABC) to the "South Midlands", including Oxford, Swindon, Newbury and Marlborough on 405-line VHF, using Channel 12 (Band III). It was not used for any broadcast services for a decade after the closure of 405 line television in 1985. However, in 1995 a low power VHF FM filler for the four national BBC radio networks was added (at 125 watts, vertical polarisation only), improving reception along the M4 corridor between Newbury and Swindon. In January 2003, a DAB transmitter was added for the NOW Swindon & Wiltshire multiplex. The BBC added a signal for its national DAB services in 2009. The mast also hosts transmission equipment for numerous mobile telephone networks. The mast is a highly visible landmark and can be clearly seen from The Ridgeway, White Horse Hill and most of the Lambourn Downs, making it a useful reference point for hikers, ramblers, and aircraft following visual flight rules. The red safety lights which mark the structure at night become visible for eastbound M4 motorists from as early as Swindon East (Junction 15), and for those travelling Westbound on the M4, it is visible as early as Junction 13 and Chieveley Services.

Membury services is a motorway service station on the M4 motorway, located on the original site of RAF Membury in the civil parish of Lambourn in the English county of Berkshire, close to the border with Wiltshire, 4 miles (6.4 km) west of Junction 14. It is owned by Welcome Break and is situated adjacent to the Membury Radio Mast.
