There is no single prescribed walking route, which is part of the charm. The old town is compact — you can walk from one edge to the other in twenty minutes — but the density of interesting buildings rewards a slower pace. Streets like the Wordgasse, Blasiistrasse, and the lanes around the Münzenberg reward wandering without a particular destination.
What makes Quedlinburg unusual is the survival rate. Many German timber-frame towns lost their oldest buildings to fires, modernisation, or wartime bombing. Quedlinburg avoided all three in ways that were partly luck and partly the town's relative economic obscurity. The result is that you can stand in front of a 14th-century house on a working residential street, with medieval neighbours on both sides, in a way that is genuinely rare. A free town map from the tourist office marks the most notable individual buildings.
