Nutwell in the parish of Woodbury on the south coast of Devon is a historic manor and the site of a Georgian neo-classical Grade II* listed mansion house known as Nutwell Court. The house is situated on the east bank of the estuary of the River Exe, on low-lying ground nearly contiguous to the water, and almost facing Powderham Castle similarly sited on the west bank. The manor was long held by the powerful Dynham family, which also held adjacent Lympstone, and was according to Risdon the site of their castle until John Dynham, 1st Baron Dynham (1433-1501), the last in the male line, converted it into "a fair and stately dwelling house".
In the Domesday Book of 1086 Noteswille was held in chief by one of King William II's thanes named Donne (or "Dunn"), who also held from the king the manor of Newton St Cyres.
The manor of Nutwell, together with nearby Harpford, were granted by King Henry I (1100-1135) to Geoffrey I, Sire de Dinan, lord of Dinan, near St Malo in Brittany. In 1122 Geoffrey granted Nutwell and Harpwell to the Abbey of Marmoutier at Tours for the benefit of the dependent priory of St Malo at Dinan. The grant was jointly made with his sons, including his eldest son Oliver I de Dinan (d.1150) and was confirmed by his wife Orieldis. Oliver I's eldest two sons Geoffrey II and Oliver II, co-founded Hartland Abbey in 1168/9. Nutwell descended to Geoffrey I's grandson Rolland de Dinan, lord of Bécherel Castle, (about 20 km SE of Dinan) the son and heir of Geoffrey I's younger son Alan de Dinan (d.1159). Nutwell was described as "land of Rolland de Dinan" in 1168, but had been taken into the king's hands and produced revenue for the royal exchequer of 14s, accounted for by the Sheriff of Devon.
