In the innermost parts of the town a wide selection of half-timbered buildings from at least five different centuries are to be found (including a 14th century structure one of Germany's oldest), while around the outer fringes of the old town there are wonderful examples of Jugendstil buildings, dating from the late 19th and early 20th centuries.
Since December 1994 the old town of Quedlinburg and the castle mount with the collegiate church are listed as one of UNESCO's World Heritage Sites. Quedlinburg is one of the best-preserved medieval and renaissance towns in Europe, having escaped major damage in World War II.
In 2006 the Harzer Schmalspurbahnen Selketal branch was extended into Quedlinburg from Gernrode giving access to the historic steam narrow gauge railway, Alexisbad and high Harz plateau.
The castle and the cathedral still towers above the city the way they dominated the town in early Middle Ages. The cathedral is a prime example of German Romanesque style. The Domschatz, the treasure containing ancient artefacts and books, was stolen by an American soldier and finally bought back to Quedlinburg in 1993 and is again on display here
