The construction of the new glass roof began in June 2019 for a period of one year, a year after the start of renovation work on the shopping center near the Place de la Comédie.

Made of EFTE material, this 120-meter long and 20-meter-tall membrane, is very resistant and translucent but not sensitive to UV rays.

This unique piece is designed especially for the Montpellier Polygon and it will be silk-screened to control the luminosity. At night, LEDs installed on the lower side will illuminate the entire glass roof.

In addition, the renovation of the Polygone is continuing to improve the standards of the parking lots, new escalators and elevators. it is also renovating the shops and the facades, while ensuring that the center remains open at all times.
