On the quay in Alkmaar you can see the statue of an important man in the history of the city: Adriaan Antonisz. As a fortification engineer, he designed many Dutch city defenses during the Eighty Years' War against Spain.
A mysterious old map of his hand has been found, pointing to an ancient defense tactic: a large secret underground gunpowder storage. But it is still there... A potential bomb in the city! Can you help in finding that bomb?

Route along beautiful places in the city where we would normally have walked by. Nice varied assignments. We also really liked that there is no time limit and we could have lunch during the tour on a terrace, and then continue again.

What a great activity! The city where we have been coming for thirty years viewed in a completely different way. All riddles can be solved, but certainly not by themselves! By having to search for things along the way, you suddenly see completely different things!
