We have included this visit as it is one of the most fascinating Christmas Experiences that one can enjoy. For over 15 years the quaint town of Gengenbach in Baden-Württemberg has transformed its entire Rathaus (Town Hall) into the world’s largest Advent Calendar House. The 24 windows (two rows of 11 plus 2 in the roof) are each decorated with a festive Christmas scene with a new window revealed every night until Christmas. Highlight: Arrive on time to see the Advent Calendar Window light up
