A collection of keyboard instruments
The former museum organisation describes a collection of harmoniums and related keyboard instruments. That collecting area continues to exist, but this does not mean that the old museum premises can still be visited.
Looking further at Geelvinck
For information about the instruments, the organisation refers to Museum Geelvinck and an online collection presentation. These are the appropriate starting points for finding out which instruments are described or on display.
A depot is not a permanent public gallery
The information also mentions storage and possible viewing on guided tours. A depot location that is mentioned is therefore not a place you can visit freely. Before you set off, get confirmation of which collection can be seen on which date.
Before you go
No museum access in Barger-Compascuum any more. Any current opportunity to visit elsewhere must be confirmed through Museum Geelvinck.
