Muncaster Castle is owned by the Pennington family, who have lived at Muncaster for at least 800 years. The Muncaster estate was granted to Alan de Penitone in 1208. The oldest parts of the castle include the Great Hall and the 14th century pele tower, a type of watch-tower fortification unique to the English-Scottish border region.
