Avebury is the site of a large henge and several stone circles surrounding the village of Avebury in the English county of Wiltshire. It is one of the finest and largest Neolithic monuments in Europe, about 5,000 years old. Although older than the megalithic stages of Stonehenge 32 kilometres (20 mi) to the south, the two monuments are broadly contemporary overall. Avebury is just off the main A4 road on the northbound A4361 towards Wroughton. The henge is a Scheduled Ancient Monument and a World Heritage Site. Avebury is a National Trust property.
The Science Museum
The Science Museum at Wroughton is a Second World War maintenance airfield in Wiltshire and has been occupied by the Science Museum since the 1970s. Six original aircraft hangars house items from the science, engineering, transport and agricultural reserve collections. There is also a research store, built in 1993, which has a stable environment and is ideal for sensitive objects. These are working stores and, as such, are not open to the public except for pre-booked behind-the-scenes tours during the summer months and occasional special events.
