The museum was closed for visitors during the renovation. Parts of the collection will be divided over other locations in Leiden during the year and a half, which means that the museum is still operational and will occasionally exchange collections. During the renovation, the collection must therefore not only be kept in good condition by ensuring the perfect climate, the collection must also remain accessible to the employees.

When the museum opens its doors again, a beautiful atrium with a ceiling of about 40 meters high will lead the visitor past the varying exhibitions. This means that the old atrium will change considerably, just like the functions of the rest of the building.

There is currently being worked on the foundation of the ground floor and on prefab constructions for the façade. Approximately 35 people work on the preparation of the installations, which will change into a team of approximately 200 people during the execution to have the (re)construction proceed as quickly as possible. ULC is working with Kuijpers on 3D models in Revit to realize a future view together with other construction partners. Incidentally, you can follow the construction closely via the webcam that Naturalis has enabled. Curious? Click here
