Dorotheum
The Dorotheum , established in 1707, is one of the world's oldest auction houses. It has its headquarters in Vienna on the Dorotheergasse and is the largest auction house in both Continental and German-speaking Europe. Besides auctions, the retail sector also plays a major role in Dorotheum's business. In the Dorotheum, works of art, antiques, furniture, and jewellery from various centuries are put up for auction. The building is constructed in the neo-classical style. It is an attraction for Viennese natives and numerous tourists alike.
Branches exist in Vienna in the Austrian states, the Czech capital of Prague, and the Italian cities of Milan and Rome, as well as in Düsseldorf, Munich and Brussels.
