The project ran almost three times over budget, costing Luttrell more than £1,200. In the 1640s the English Civil War broke out between the supporters of King Charles I and Parliament. Thomas Luttrell, George's eldest son, initially supported Parliament and after the outbreak of war William Russell, the Duke of Bedford and Parliamentary commander in Devon and Somerset, ordered him to increase the garrison at Dunster to resist a potential Royalist attack.
Dunster cross has an octagonal base and polygonal shaft, however the head of the cross has been lost. It stands on a small area of raised ground on a plinth. The socket stone is wide and high. The surviving shaft is high and changes from square to octagonal as it rises. There is an inscription on the northern face which says "WC, 1871, WS" recording a restoration. It is in the care of English Heritage for the state and managed by the National Trust. Other notable buildings include the Nunnery, Dunster Watermill, Dovecote and the Priory barn, which belonged to Dunster
