Supreme Headquarters Allied Powers Europe (SHAPE) is the central command of NATO military forces. Since 1967 it has been located at Casteau, north of the Belgian city of Mons, but it had previously been located, from 1953, at Fontainebleau, France. From 1951 to 2003, SHAPE was the headquarters of operational forces in the European theatre (Allied Command Europe, ACE), but since 2003 it has been the headquarters of Allied Command Operations (ACO), controlling all allied operations worldwide.
