Cell towers in Versailles (Yvelines)

Declared supports include 2 water towers, 2 churches or religious buildings and 1 historic monument, with buildings making up most of the remainder.

Masts stand at Aile du Midi, Butte Gobert, Porte du Bois Robert, 24 rue Réservoirs, 1 rue Lucien Sergent and Résérvoir de Satory.

Over the past 12 months ANFR recorded 46 new systems here. ANFR has approved 3 new sites that are not live yet, plus additions on 22 existing masts. New: Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 46-44 Rue Albert Joly, Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 2 Rue Antoine Coypel and Orange (4G and 5G, including 5G at 3.5 GHz) at 21 Rue Jouvencel. 36 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (46 of 62), so heights stay modest; the tallest support is 60 m at 1 Rue de l'Etang du Désert.

Systems from 1992 are still on the register. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in December 2020, SFR followed in March 2021. 2013 was the busiest year, with 123 new systems, most of them 4G.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 14 of its 27 masts, Orange on 14 of its 25 masts, Free Mobile on 12 of its 17 masts and SFR on 7 of its 22 masts. 5G is on 69% of masts here, against 88% across Yvelines towns with five or more masts.

Among the 62 Yvelines towns with at least five masts, Versailles ranks 1st by mast count.

Viroflay lies 2 km to the east and has only 5 masts.

Only one mast carries all four networks.

At 26 km² with 84,095 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the CA Versailles Grand Parc (CAVGP) intercommunal grouping.

Figures above cover installations declared to ANFR as in service or technically operational, as of October 2026; approved projects are not counted.
