Dovecot at Blackford Farm
United Kingdom
The 186th tallest tower in the world
The Dovecot At Blackford Farm in Selworthy on Exmoor within the English county of Somerset was probably built in the 11th century. It is a Grade II* listed building, and scheduled monument. The cylindrical stone dovecote has a cone shaped roof. It contains over 300 nest boxes. The pigeons would have been domesticated for food, possibly by Montacute Priory or by the local lord of the manor. It is now owned by the National Trust and used as a store for the neighbouring farm.
