Once the Roman town of Brigantium, Bregenz is now a major tourist spot that`s both modern and historic. The town is located on the eastern shores of Lake Constance. The modern part of town lies along the lake`s shore, and the old town rises above it. Bregenz is especially famous for the annual summer music festival Bregenzer Festspiele. The first settlements in the area of present-day Bregenz were established around 1500 BC. In the Celtic period (from around 500 BC), Bregenz was one of the most strongly fortified places in the region. After the Romans conquered the area, they built the city of Brigantium, a civilian city with a forum, temple district, market halls, a basilica and more.
