The object of the project is the rehabilitation and restoration of the decaying and today, or inappropriately used ground floor, basement and cellar spaces of the Imperial Palace and the eastern part of Purkrabství of the Karlštejn NKP Castle. These new premises will be made available to the public by opening new exhibitions, holding events in a multipurpose hall and in the garden on the park. The subject is also the construction of new networks and a modern visitor centre and security of the monument. All of this is an essential step in terms of the concept of the restoration of the castle.
