Nether Stowey Castle, also known locally as The Mount, represents a masterwork of Norman motte-and-bailey design constructed in the 11th century in the Quantock Hills village of Nether Stowey, Somerset. Built by Alfred of Spain or his daughter Isabel according to Domesday references, this fortress consists of a square keep—possibly stone or timber on stone foundations—defended by an outer and inner bailey with impressive earthworks. The motte rises 29 feet above a 6-foot-wide ditch that descends 7 feet deep, creating formidable medieval fortifications. Positioned dramatically between the village and the Quantock Hills with spectacular views across the Bristol Channel, the site has been designated a Scheduled Ancient Monument with its keep foundations listed as Grade I, preserving one of the finest examples of Norman military architecture in the West Country.
