Cell towers in Garches (Hauts-de-Seine)

Antennas are listed at 129 Rue de Buzenval, 20 rue de Suresnes, Villeneuve, 5 Allée des Belles Vues, 7 rue des Quatre Vents and 23 Rue du 19 Janvier.

Most antennas sit on rooftops (10 of 10), so heights stay modest; the tallest support is 27 m at 129 Rue de Buzenval.

2 masts belong to the commune itself; the rest sit mainly on private buildings.

Systems from 1996 are still on the register. Local 5G started with Bouygues Telecom in November 2020; Free Mobile followed in March 2021, SFR followed in September 2021. 2018 was the busiest year, with 18 new systems, most of them 4G.

Approved additions not yet in service are pending on 3 existing masts, for example Free Mobile (4G and 5G, including 5G at 3.5 GHz), Free Mobile (4G and 5G, including 5G at 3.5 GHz) at 23 Rue du 19 Janvier and Orange (4G 700 MHz) at 20 rue de Suresnes. 5 Bouygues Telecom 5G transmitters are listed as technically operational — installed, but not yet declared commercially in service.

On 3.5 GHz, the fastest 5G band: Bouygues Telecom on 2 of its 3 masts, Free Mobile on 2 of its 3 masts, Orange on 2 of its 4 masts and SFR on 1 of its 5 masts.

Saint-Cloud lies 1.6 km to the east and has 33 masts, more than here.

Colocation covers 4 supports.

Among the 36 Hauts-de-Seine towns with at least five masts, Garches ranks 32nd by mast count.

At 3 km² with 17,743 residents, the commune is dense enough that most antennas sit on rooftops rather than pylons. It is part of the Métropole du Grand Paris intercommunal grouping.

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