Admission: Free to view (managed heritage site); public access to the summit is restricted

Silbury Hill is a large prehistoric chalk mound on the Marlborough Downs in Wiltshire, England, built in the late Neolithic period around 2400-2300 BC. It is the largest man-made prehistoric mound in Europe and an important archaeological landmark.

The mound rises to roughly 39-40 metres and consists of compacted chalk and earth laid in successive layers; archaeological investigations have not revealed a burial or chamber. The hill forms part of the broader prehistoric landscape around Avebury, which includes stone circles, barrows and linear earthworks.

Excavations and studies since the 18th century have investigated construction techniques and internal structure, and conservation works have been carried out to stabilise the mound. Its precise purpose remains a subject of research and debate among archaeologists.

Silbury Hill sits on open chalk downland near Avebury in Wiltshire, within a complex of Neolithic monuments. The site is managed for conservation and is accessible by short walks from nearby lanes and the Avebury monument area.

• Date and significance: Constructed around 2400-2300 BC, it is the largest prehistoric artificial mound in Europe and contains no known burial chamber.
• Size and composition: The hill rises to about 39-40 metres and has a roughly circular base with a substantial volume of compacted chalk and earth, visible from the surrounding downland.

Silbury Hill sits beside the Avebury stone circle in Wiltshire. By road it’s reached via the local lanes off the A361/A4361 around Avebury; there is a public car park in Avebury village and the hill is a 5-10 minute walk from the village/car park. The nearest mainline railheads are Swindon and Pewsey; from those towns visitors use local buses or taxis to reach Avebury.

• Go early morning or late afternoon from the nearby Avebury car park for the best light and quieter walks; Silbury Hill itself is fenced and cannot be climbed, so enjoy the mound from the surrounding paths and viewpoints.
• Approach on foot via the Avebury stone circle and the public footpaths rather than trying to drive to the closest roadside-this gives better context with neighbouring prehistoric monuments and avoids limited roadside parking.
• Most visitors miss the wider Neolithic landscape: include a short walk to nearby West Kennet Long Barrow or the Ridgeway viewpoints to understand the interlinked sites rather than focusing only on the mound.
