Sites d'émission de la Croix de Guizay, Television and radio broadcasting facility in Planfoy and La Ricamarie, France

Sites d'émission de la Croix de Guizay is a broadcasting complex in the Saint-Étienne region with two towers of different heights. The Towercast tower stands approximately 67 meters tall, while the TDF tower reaches about 110 meters and is visible from the surrounding hills.

The site's documented history centres on the analogue switch-off: on 22 September 2010 Canal+ stopped analogue broadcasting in Rhône-Alpes, and the remaining channels followed on 15 June 2011. The TDF installation at Planfoy now carries seven digital terrestrial multiplexes, while the Towercast mast at Fond de l'Écuelle, in La Ricamarie, is used for FM radio.

The two sites carry different station counts: the Towercast mast at Fond de l'Écuelle relays 16 FM radios, while the TDF installation on the chemin de l'Antenne carries 10 FM radios plus the seven TNT multiplexes. The Towercast mast also holds FH receivers that pick up the studio feed of some local stations during their opt-outs.

The two installations lie in different communes: the TowerCast mast at Fond de l'Écuelle in La Ricamarie, the TDF site on the chemin de l'Antenne in Planfoy. Both are fenced technical areas with no public access, so the structures are seen from outside, from the roads and slopes of these two communes.

The two sites sit in different communes: the 67-metre TowerCast mast stands at Fond de l'Écuelle in La Ricamarie, while the TDF installation on Chemin de l'Antenne in Planfoy reaches 110 metres, with a separate 42-metre Orange microwave tower. Together they carry 26 FM stations.
