It’s hard to believe the fine old Orczy manor house that now holds the lion's share of the Mátra Museum began as a family hunting lodge in the 1760s. Here you'll find exhibits dealing with the history of Gyöngyös in the 18th and 19th centuries, area ethnography and a room dedicated to the 1800 local Jewish Holocaust victims, as well as minerals and fossils (including a mini mammoth). In the new Natural History Pavilion there are copious amounts on animal and plant life as well as a palm house and aquarium. The displays at this award-winning museum are all very well done, with English summaries. A combined ticket costs adult/child 1550/750Ft. City lore has it that the wrought-iron railings enclosing the elaborate flower gardens were made from gun barrels taken during the kuruc uprising.
