With its lacy spires, cheeky gargoyles and intricate entrance portal, Freiburg’s 11th-century minster cuts an impressive figure above the central market square. It has dazzling kaleidoscopic stained-glass windows that were mostly financed by medieval guilds and a high altar with a masterful triptych by Dürer protégé Hans Baldung Grien. Square at the base, the tower becomes an octagon higher up and is crowned by a filigreed 116m-high spire. On clear days you can spy the Vosges Mountains in France.
Closer to the ground, near the main portal in fact, note the medieval wall measurements used to ensure that merchandise (eg loaves of bread) were the requisite size.
Note that the cathedral is closed for visits during services (exact times are available at the info desk inside).
