Châteaux de Ternier, Medieval fortress ruins in Saint-Julien-en-Genevois, France.
The Ternier Castles consist of two distinct fortresses situated on a 490-meter hillock, controlling the route between Geneva and Chambéry.
The castles date back to the 13th century, with the comtal castle belonging to Geneva counts and La Poype fortress owned by the Ternier family.
The site includes remnants of two main towers, ancient walls, and a chapel dedicated to Saint Nicholas within the La Poype fortress enclosure.
The ruins can be accessed through walking paths leading up the hill, with an information panel installed by the local Rotary Club.
The castle walls reached heights of 21 meters with 2.8-meter thickness, demonstrating advanced medieval military architecture techniques.
