As you walk south out of Rothbury, you are heading to the small hamlet of Whitton. This path passes through the hamlet and heads towards the looming hills of Simonside. However you soon come across Sharps Folly. A folly is a decorative piece of architecture with no discernible use. This folly was erected by the Reverend Dr Thomas Sharp, Rector of Rothbury 1720 – 1758. It was built for the relief of unemployment amongst local stonemasons and used as an observatory. It is the oldest folly in the county and a listed building.
