The Federal Building Agency has announced a public tender for the restoration of the façades of the Palais des Princes-évêques in the Walloon city of Liège.
The restoration work, set to begin in phases from 2028, will be spread over at least 12 years, the agency stated on Monday. It will cost around €20 million.
Following a 2023 agreement between the Federal Building Agency and the Walloon Region, both co-owners, a public tender has been launched to select the contractor for the restoration studies and the specifications for the first phase of the project.

The restoration will take place in six stages.
The works will start with the first inner courtyard, followed by Place Saint-Lambert, Place Notger, Espace Tivoli and the third courtyard, Rue du Palais, and finally the second courtyard.
The aim is to launch the project in the second half of 2025. The actual restoration work will begin in the second half of 2028.
