Potton is a small market town just a few miles east of Sandy, near the Cambridgeshire border. The town belonged to the Earls of Huntingdon in the Middle Ages and held a market here as early as 1200. Until the early 20th century the village was home to a horse fair that attracted visitors from across the county.
The parish church of St. Mary the Virgin is an enjoyable 13th century building featuring a rod staircase.
The RSPB national headquarters is located midway between Sandy and Potton, in an attractive tract of 100 acres of woodland, with nature trails through the woods and facilities for wildlife and bird observation.
