Grendelbruch

From 25/11/2026 to 06/01/2027

From 25 November to 6 January, set off on an adventure through 57 villages and towns in Alsace! Your mission: to find, step by step, the Christmas Sparks scattered across the region to let the Alsatian Christmas Flame shine. One of these Sparks is hidden right here… Can you find it?

Welcome to Grendelbruch, adventurers of the Alsatian Christmas Flame! A Spark of the Flame is said to have left its mark in this village nestled in the heart of the Magel valley. To pick up its trail, you’ll need to take an interest in one of the treasures of its history: the ruins of Alsace’s oldest fortified castle, situated very close to Grendelbruch!
