La commune actuelle de Geyssans se compose de deux anciennes paroisses et seigneuries, celle de Geyssans et celle de Saint-Ange, réunies seulement dans le dernier tiers du XVIIIe siècle par les Bally de Bourchenu, seigneurs de Triors.
Number of inhabitants: 600
Area: 1.090 ha.
Situated 8 km north-east of Romans, on that section of the Drôme des Collines hills formed by the south-west slope of Les Chambarans, the Geyssans district is crossed by two watercourses, the Savasse, a trout river, and the Drivette.
The activities of this undulating land are essentially agricultural (cereal crops and livestock). The diversity of its landscapes, forests, hillsides and streams comprise a particularly attractive living environment.
Geyssans has had many names over the centuries: "Gissanium" in 950 AD, "Geissans" in 1200, "Jaisas" in 1250, "Dominus Geyssani" in 1350, "Jeyssano" and "Jayssain" in 1500, and finally Geyssans since 1775.
In the Middle-Ages, Geyssans formed part of Saint-Marcellin, a parish attached to the diocese of Vienne. Its church, dedicated to Saint Martin of Tours, was built in 1895. It came under the Chapter of Romans.
Sights to see:
The "château": A former manor house belonging to the estate of the Countess of Triors and forming part of the Earldom of Paris, it is situated on the road leading to Saint-Ange (very beautiful church).
