How a medieval fortress evolved into a Victorian mansion and modern tourist attraction
In short: Dunster Castle began as a strategic Norman motte and bailey fortification, designed to pacify Somerset and guard the coast. Over nine centuries, it transformed from a military stronghold into a lavish family home, eventually becoming a National Trust property that blends ancient stone walls with modern environmental technology.
Established by William de Mohun following the 1066 Norman Conquest, Dunster Castle was built on a 200-foot-high hill known as the Tor. Its initial design served as a vital caput for controlling the coastal road and defending against sea-borne attacks. By the 12th century, a stone shell keep replaced the original timber structures, and the site survived a significant siege during the Anarchy in 1138. The Luttrell family, who acquired the property in the late 14th century, would oversee its most dramatic transformations over the next 600 years.
The castle’s military utility ended after the First English Civil War. In 1650, Parliament ordered the slighting of its defences, leaving only the Great Gatehouse and fragments of the Lower Ward towers. This destruction allowed the Luttrells to pivot toward domestic comfort. In 1617, they constructed a Jacobean mansion within the old walls, which was later extensively remodelled in the 1860s and 1870s by architect Anthony Salvin. Salvin’s work aimed to create a Picturesque, Gothic aesthetic, incorporating advanced features like wrought-iron beams, gas lighting, and a massive 40,000-gallon underground reservoir.
Financial pressures eventually forced the family to relinquish control. Following the death of Alexander Luttrell in 1944, crippling death duties led to the sale of the estate. Although the family briefly reacquired the castle in 1954, Colonel Sir Walter Luttrell eventually gifted it to the National Trust in 1976. Today, the site serves as a unique historical record, where visitors can see everything from 13th-century gates to 20th-century polo grounds. The Trust has even integrated modern sustainability, installing solar panels behind the battlements in 2008 to reduce the carbon footprint of this Grade I listed monument.
