Greisinger (Tolkien) Museum

The museum, located in Jenins, Switzerland, opened October 4, 2013.

It houses the Greisinger Collection, Bernd Greisinger's private collection on the subject of Middle-earth.

It is the largest and most important of its kind in the world, consisting primarily of art and literature along with collectors' items of all kinds.

From the museum website:

The construction of the museum started in mid-2008.

The planning and execution of the museum were geared towards the optimized use of the Greisinger Collection.

All rooms offer visitors the feeling of being in Middle-earth due to their ambience.

The door of the hobbit cave leads to the museum, most of which is underground.
