This intriguing hexagonal building once housed washbasins for monks. It was built by Abbot John Meere in the 16th century within the cloister of Sherborne Abbey. Medieval monasteries were noted for their plumbing. Monks had water piped into the monastery by complex systems. While most such structures were destroyed at the dissolution of the monasteries, this conduit survived by being moved outside the abbey for the benefit of local people. Its rarity has made it a Scheduled Ancient Monument.
