September 3, 2025 - Unfortunately, HERMON Heritage will not be opening any monuments to the public during Open Monument Day this year. Our projects are currently either in the implementation phase of restoration and redevelopment, or still too far in the preparatory stages to receive visitors.
Would you still like to see some of our projects? Visit the De Schat van Simpelveld website for the current opening hours of this museum, located in our New Loreto project.
Would you like to discover other monuments this year? On the Open Monument Day website, you will find an overview of the many special locations that are accessible.
Update September 10: New Loreto will open its doors after all. More information can be found on the Open Monument Day website.
