Silbury Hill is one of the most mysterious and impressive prehistoric monuments in the United Kingdom. Located near Avebury in Wiltshire, it is the largest man-made prehistoric mound in Europe. This enormous chalk mound stands around 30 meters (98 feet) high and covers an area of about 2 acres. Its sheer size and the effort required to build it have fascinated archaeologists and visitors for centuries.
Unlike other ancient monuments, the exact purpose of Silbury Hill remains unknown, adding to its enigmatic charm. It is believed to have been constructed around 2400 BC during the late Neolithic period. Despite many archaeological investigations, its function still puzzles experts, with theories ranging from a ceremonial site to a burial mound or a territorial marker.
Silbury Hill is easily accessible and is located close to the village of Avebury and the famous Avebury Stone Circle.
Wiltshire experiences a temperate maritime climate with mild summers and cool winters.
Silbury Hill is an open-air site that can be visited all year round. There are no formal opening or closing hours since the mound itself is accessible at all times.
However, nearby facilities such as the Avebury visitor center, parking, and toilets have standard opening hours which are typically from 9:30 AM to 5:00 PM during peak seasons, and shorter hours in winter. It is recommended to visit during daylight for safety and to fully appreciate the views.
Silbury Hill’s fame comes from its extraordinary size, age, and mystery. It is the largest prehistoric mound in Europe and one of the largest in the world. Constructed entirely from chalk and earth, it is estimated that around 248,000 cubic meters of material were used, which would have required the labor of hundreds of people over many years.
Unlike other Neolithic monuments, Silbury Hill has never been excavated fully, and no burials have been found inside, which makes its purpose unique and still debated. Some theories suggest it was a ceremonial or ritual site, possibly linked to surrounding sacred places like Avebury’s stone circles.
The hill has been a subject of folklore, archaeological study, and visitor curiosity for centuries, making it a symbol of Britain’s rich prehistoric heritage.
Visiting Silbury Hill does not require an entry fee, as it is part of the National Trust properties around Avebury.
Silbury Hill was constructed in several phases over a few hundred years around 2400 BC. It stands about 30 meters high and 160 meters in diameter at the base, made entirely from layers of chalk, earth, and clay.
Unlike burial mounds or barrows from the same period, Silbury Hill contains no evidence of burials or grave goods. This absence has puzzled archaeologists and led to many theories about its original function.
The mound is surrounded by a ditch and bank, common features in Neolithic ceremonial sites, and sits within a landscape rich with other prehistoric monuments such as Avebury’s stone circles and West Kennet Long Barrow.
Archaeological excavations have been limited to preserve the site, but small investigations have revealed evidence of construction techniques and some wooden posts, hinting at ritual use.
