The area surrounding Roseto is mountainous with the river Fortore running through the town. Hence the name Valfortore (valley of the Fortore). The hills surrounding Roseto are populated with electric power windmills.
There have been numerous waves of migrations from the town of Roseto Valfortore over the past century. One of the first waves of immigrants to settle in the United States of America took place in the early 1880s. They settled in the Lehigh Valley of Pennsylvania and created the settlement of Roseto, that was eventually incorporated in 1912. Throughout the 1950s and 1960s more than 3,000 Rosetani migrated to Toronto, Ontario and its surrounding areas as well as Washington D.C. In the 1920s, 1930s, 1940s and 1950s it was recorded that many migrated to Youngstown, Ohio and surrounding areas. Many migrants worked in the steel mills around Ohio.
