For the visual treat of a lifetime, you definitely need to check out the Dom Museum VIenna. This fantastic gem, located right next door to St. Stephen's Cathedral, displays precious church treasures and contemporary art. The historic building has been remodeled. It offers a fantastic view of St. Stephen's Cathedral, which provides a fascinating contrast between the old and the new.
Some of the historic treasures you'll find in the Dom Museum include those of Vienna's St. Stephen's Cathedral, the archdiocese of Vienna, and the avant-garde classics from the collection of Otto Mauer, including the world-famous portrait of Duke Rudolf IV, considered one of the most realistic portraits in the Western World. Rudolf IV is actually buried next door in the catacombs of St. Stephen's Cathedral. Alongside the permanent historical exhibition, there are two special exhibitions each year dealing with current and relevant topics about society, religion and art.
