The State is working on the restoration of the Romanesque dome (1180-1200) which covers the transept crossing of the Strasbourg Cathedral. This dome has suffered from damage due to its exposure to the elements since the construction of the lantern tower of the Klotz tower, in the 1870s.
An unusual scaffolding, suspended
The work, commissioned by the DRAC Grand Est under the mastery of the chief architect of historic monuments Pierre-Yves Caillault, began with the installation of a scaffolding suspended above the choir from the eight windows of the frame. The company Europe scaffolding completed this extraordinary structure in September 2022.
Initial pre-restoration work, Winter 2022-2023
The vault is purged and cleaned: purging of the cement on the top (outer side) of the dome and dusting of the bottom (inner side) – Chanzy-Pardoux Company.
The restoration tests were carried out: desalination tests by compresses – BPE laboratories.
The study of brick and stone masonry by a team of building archaeologists under the direction of Heike Hansen is underway: the archaeological survey of the building will be completed at the end of January 2023.
This project, which began in April 2022 with the complex assembly of scaffolding, will be completed in 2024.
It is fully funded by the DRAC Grand Est for 1.7 million euros.

La voromanesque
The large dome (made between 1180-1200) covers the choir of the Strasbourg Cathedral.
Of Romanesque design, it is thus the crypt and apse, dated from the first phase of the reconstruction of the church, which lasted nearly 300 years until its completion in XVe century.
Its restoration, implemented by the DRAC Grand Est, under the mastery of the chief architect of historical monuments (ACMH) Pierre-Yves Caillault, meets both a sanitary necessity and a desire to valorize.
