Mainz Sightseeing Treasure Hunt and Walking Tour: Gutenberg and the lost relic
Mainz, 1430. The city is on the brink of chaos. As young Johannes Gutenberg, you carry more than ink-stained fingers—you carry the fate of your family’s name and the future of the written word.
Patricians clash with guilds, and the relic of St. Martin, lost to time, may be the only key to peace. Solve clues hidden in ancient alleyways, follow whispers of history through cobbled streets, and retrace the steps of a legend.
This outdoor quest is a walking puzzle woven into the fabric of Mainz, where every discovery brings you closer to the relic—and to saving your legacy. Play with friends or family and create a story worth printing.
