Curious museum piece from castle Loevestein in Holland

this chest was standing in the slot loevestein museum for as long as i can remember. My aunty was a Guide over there and i loved to visit her and the beautifull castle the story is that it use to be a prisson for Hugo the great who escaped by hiding in a chest of books. Ofcours this aint the original chest but this chest was standing in one of the rooms. I asked my aunty a lot but never asked here about this chest with the special lock. She sadly pased away.
A few years back to my regret they mordernist the museum to make it more apealing for the younger generations now many years later we got this for me memorabele lovley chest from out of the attic but knowone nows wether it is just old, where it is originally from and what it use to hold so here is my question who knows something about this chest of its age or maker its not about what is worth because the memories for me are priceless but would love to get some directions where to look or backstory:-) when you visit the nethelands Just tell me and i give you an old school guidingtour trough and about the slot loevestein:-) sorry for my poor writing
