An architectural ensemble from the 12th and 15th centuries, the Manor of Deil, at Allaire, in Morbihan, is only accessible to groups, upon written request. Listed as a Historic Monument, it still reveals a circular corner tower from the 15th century.
The Manor of Deil is made up of several buildings built around a large rectangular courtyard. Revamped and embellished in the 17th century, the site was then embellished with a Louis XIII style pavilion, an octagonal dovecote, a fountain and a washhouse.
