Stresa (strā´zä), town (1991 pop. 4,684), Piedmont, N Italy, on the western shore of Lake Maggiore. Its lovely gardens and villas and the scenic Borromean Islands nearby have made it one of the most popular resorts in the Italian lake country. In 1932 a conference of 15 European nations on economic collaboration was held at Stresa. At another conference held (1935) in Stresa, Great Britain, France, and Italy made (but never implemented) a decision to maintain a common posture toward Germany, which had begun to rearm in violation of the Treaty of Versailles.
