 The Tour was equipped with forty cannon, but Vauban's other improvements were not carried out.Nonetheless, in 1707, during the War of the Spanish Succession, the Tour helped Toulon to successfully resist a combined attack and siege by a British-Dutch fleet and the army of Eugene of Savoy.In 1770, a new fort, Fort Lamalgue, was constructed at the harbor entrance, the Tour Royale was no longer as important for the defense of the port.
