Vienna offers an inexhaustible wealth of architectural grandeur, a rich artistic legacy and some of the finest museums in the world. Today, it has just 1.8 million inhabitants, but the immense Hofburg Palace, seat of the Habsburg imperial dynasty, recalls the city’s past as capital of the Austro-Hungarian Empire. Most places are within easy reach, and if your legs become weary, there are always the spotless red-and-white trams that constantly trundle around the Ringstrasse, the great circular boulevard that defines the Innere Stadt, or old city. And perhaps only Paris can boast as many delightful cafés.
