Cell towers in Nantes (Loire-Atlantique)

Most of the town's 190 masts are buildings (145); 7 churches or religious buildings and 1 water tower make up the rest of the mix.

Masts stand at Parc Expo la Beaujoire, rue du Moulin Parking Decré, rue du Marechal Joffre, Stade de la Beaujoire, Allée Jacques Berque- quai de Malakoff- Resid Home Stade Sa and 38 boulevard Antoine Watteau.

Over the past 12 months ANFR recorded 139 new systems here. ANFR has approved 33 new sites that are not live yet, plus additions on 48 existing masts. New: Bouygues Telecom (4G and 5G) at 12 Rue du Champ de Tir, Bouygues Telecom (4G and 5G) at 17 allée Bacot and Bouygues Telecom (4G and 5G, including 5G at 3.5 GHz) at 13 allée Ile Gloriette. 132 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

Most antennas sit on rooftops (145 of 190), so heights stay modest; the tallest support is 76 m at rue du Marechal Joffre.

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

Systems from 1995 are still on the register. SFR opened 5G here in November 2020; Bouygues Telecom followed in January 2021, Orange followed in March 2021. 2013 was the busiest year, with 497 new systems, most of them 4G.

15 masts carry all four networks.

Among the 65 Loire-Atlantique towns with at least five masts, Nantes ranks 1st by mast count. With 190 masts for 327,734 residents, or 6 per 10,000, it has fewer masts per inhabitant than the median for those towns (8).

On 3.5 GHz, the fastest 5G band: Orange on 64 of its 85 masts, SFR on 64 of its 76 masts, Bouygues Telecom on 57 of its 83 masts and Free Mobile on 50 of its 61 masts.

3.2 km to the south, neighbouring Reze has only 28 masts.

At 66 km² with 327,734 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Nantes Métropole intercommunal grouping.

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