The Dover Patrol Monuments are a trio of war memorials designed by Sir Aston Webb to commemorate the Royal Navy's Dover Patrol of the First World War. Two identical granite memorial obelisks, 75 feet (23 m) high, were erected near Dover and on the Cap Blanc-Nez near Calais in 1921 and 1922. A third was erected in Brooklyn, New York, in 1931. The UK monument became a Grade II listed building in August 1966, promoted to Grade II* in August 2015.
