Krellsche Schmiede is a small historic smithy in Wernigerode, the kind of place that makes the town's half-timbered streets feel worked-in rather than merely decorative. The building and workshop preserve a craft that once belonged naturally among the lanes below the castle.
It is not a large museum, so fold it into a slow walk through the old town. The reward is detail: tools, soot, timber, and the practical side of a town that otherwise risks becoming all pretty facades and Harz mountain postcards.
