The mission: Your story in Utrecht

The Utrecht wharf cellars are unique in the world. Maintaining these medieval structures is important, and during renovations archaeologists continue to make new discoveries.
Lilliana Jonas, also known as Lilly, is one of the archaeologists researching medieval treasures. You will meet her during one of her research projects along the Oudegracht. Today, however, she discovers something very special in the wharf cellars… something that might have been better left hidden.
