The world's largest floating stage, set out on Lake Constance, where the Bregenz Festival mounts colossal open-air operas each summer. It is the perfect place to begin a walk where the Alps meet the lake.

The lakeside harbour where excursion boats set off across Lake Constance and a slender lighthouse marks the tip of the flower-lined pier. From here the view opens across the water to the German and Swiss shores.

A glowing cube of etched glass on the lakeshore, the Kunsthaus Bregenz is Peter Zumthor's celebrated contemporary art museum. Opened in 1997, it is widely regarded as one of Europe's finest exhibition buildings.

A small Baroque chapel near the lakeshore, built to honour a medieval battlefield victory. It is one of the oldest sacred sites in Bregenz, dedicated to Saint George.

The unmistakable symbol of Bregenz, a medieval tower crowned by a vast bulbous Baroque onion dome. Said to be the largest of its kind in Central Europe, it houses a frescoed chapel and a small tower museum.

The gateway and surviving walls of Bregenz's medieval upper town, the Oberstadt. Pass beneath the stone arch and you step into the fortified heart of a settlement whose roots reach all the way down to Roman Brigantium.

A grand yellow half-timbered house from 1662, this is the largest Fachwerk building in Bregenz. Despite its name, it never served as the main town hall but housed the city archives and the town clerk.
