...'Set in tranquil grounds adjoining a riverside village, this rare example of an Elizabethan artillery fort was begun in 1559 and redeveloped in 1599-1601, to protect warships moored at Chatham dockyards. Despite a brave attempt, it entirely failed to do so in 1667, when the Dutch sailed past it to burn or capture the English fleet at anchor.'
