Rapunzel's Tower

Origin
Origin's unknown, it was collected by the agents of Warehouse 11. It was retrieved from the Black Forest reigon of Germany. It is currently located in the center of the Grimm Sector, where it is visible over the canopy. It was used by Marie Guichon to imprison Sandy Calecer in 2013.

Effects
The tower consists of a stone structure roughly twwenty metres high with a wooden door at the base and a room at the top with a single window. Save for the room, the rest of the tower is completely hollow. When the door to the tower is opened, instead of leading to the expected inside of the tower, it opens to the room at the top. Once the door is closed, it vanishes from the inside of the room, leaving the only means of escape through the window. This makes the tower an effective means of containing a prisoner.
