A new stage roof

The Roman Theatre of Orange was originally covered by a roof structure dating from the 14th century AD, which was destroyed by fire. From the 19th century onwards, numerous roofing projects were devised to protect the ancient façade of the great stage wall, which was rapidly deteriorating. Rainwater and bad weather were increasingly weakening this magnificent Imperial Roman building. However, it was impossible to restore the roof to its original state.

Therefore, the immense over 1000m² glass roof of the Roman Theatre of Orange is made of metal structures, which support the glass plates. This roof only weighs 200 tonnes, i.e. 50% less than a timber structure. To preserve the monument, it does not rest on the ancient stones but on a gigantic 61.70 metre long cross beam, supported by the side buildings reinforced by injections of lime into the stone.

This project perfectly preserves the unique and extraordinary acoustics of the Roman Theatre of Orange. The roof has been installed at a height of 32 metres whereas the human voice only rises to 25 metres and singing to 27. In addition, an acoustic membrane has been placed under this stage roof and acts as a “louvre”. By integrating current safety standards, the installation also serves as a support for the lighting and curtain which, concealed by a thin metal mesh, discretely fit into the decor.
