Groningen Orgelland Foundation is the expression for a special phenomenon. More and more people realize that nowhere else in the world is such a wealth of organs found in a geographically small area as the province of Groningen. A treasure that can not only be expressed in numbers, but especially also in the qualities of the individual instruments in their construction, sound, the state of playability and the high degree of authenticity of the many old to very old organs that are underneath. An almost complete overview of organ building from around 1500 to the present can be found there. This website is furtheron in Dutch language.
