Cell towers in Rouen (Seine-Maritime)

2 supports are declared underground, in a gallery or a tunnel. For questions about exposure, see the exposure guide.

Most of the town's 94 masts are buildings (70); 5 churches or religious buildings, 2 underground or tunnel sites and 1 water tower make up the rest of the mix.

Antennas are listed at St Martin Vivier Bouverie, Saint-Sever, 7 Parvis de l'Eglise St Hilaire, 7 RTE de Lyons la Forêt - rue de Repainville, 111 rue du Général Leclerc and rue Henri Ii Plantagenêt.

Over the past 12 months ANFR recorded 100 new systems here. ANFR has approved 4 new sites that are not live yet, plus additions on 31 existing masts. New: Bouygues Telecom (4G) at 8 allée Eugène Delacroix (espaces du Palais), Bouygues Telecom (4G and 5G) at 9 rue de l'Avalasse and Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 15 Place de la Verrerie. 46 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

8 masts belong to the commune itself and 3 to Hivory; the rest sit mainly on private buildings.

Systems from 1993 are still on the register. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in January 2021, SFR followed in March 2021. 2013 was the busiest year, with 160 new systems, most of them 4G.

Most antennas sit on rooftops (70 of 94), so heights stay modest; the tallest support is 70 m at place Alfred de Musset.

Among the 30 Seine-Maritime towns with at least five masts, Rouen ranks 2nd by mast count.

On 3.5 GHz, the fastest 5G band: Free Mobile on 26 of its 34 masts, Orange on 23 of its 34 masts, SFR on 23 of its 32 masts and Bouygues Telecom on 20 of its 32 masts.

Nearby, Mont-Saint-Aignan (2.3 km to the north) has only 19 masts.

Only one mast carries all four networks.

At 21 km² with 117,662 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole Rouen Normandie intercommunal grouping.

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