Spirthill is a small hamlet in the county of Wiltshire in England, situated 5 km (3.1 mi) to the south of Lyneham, it is too small to be defined as a village and has no specific 'centre'. It is on top of a hill with views over the Avon valley and the towns of Calne and Chippenham can be seen from some points.
It is a quiet community of farmland and residential housing spread out along a very narrow and unlit lane.
There are 19 homes in the hamlet, including five farms with livestock or arable crops. The area was once part of the nearby Bowood Estate and can trace historical links back to the 16th Century. It is believed there were farms in the area around the Doomsday time or before. There are no significant industrial activities in the hamlet and development is strictly controlled by local policy.
The hamlet is served by Wessex Water, Scottish and Southern Electricity are responsible for the overhead mains power supplies. The BT exchange at Hilmarton serves the hamlet via overhead telephone lines. There is no sewerage service or mains gas supply to the hamlet. There are no shops, pub or telephone box, but there is a post box (collections on weekdays and Saturdays at 4.45 PM). There are no regular public transport services, the nearest bus stops being on the A3102 at the foot of Snow Hill which is about 2 miles away. Walking these lanes requires particular care.
The Wiltshire Library Service mobile library visits regularly, using the yard of Naish House Farm.
