De missie: Jouw verhaal in Leiden

Leiden’s crossed keys are known as the keys of Saint Peter.

In this quest, they also represent hidden keys passed from one Keeper to the next:

Memory, Knowledge, Freedom, Courage and Truth.

An archivist named Elias van Rijn, has disappeared after discovering that parts of Leiden’s history were being forgotten.

Follow the trail he left across the city, solve observation-based puzzles, and restore the stories of people who were famous, forgotten, celebrated or deliberately overlooked.
