#ChateauDesAllymes #BugeyStronghold #WhatAView!
This former stronghold is an emblematic monument of the unification of Ain with the Kingdom of France in 1601, under the reign of Henry IV. An impressive military and medieval sentinel, the castle sits high above the Ain plains and can be seen from all around.

A vestige of the signing of the Treaty of Lyon

Back in the 16th century, René de Lucinge, the ambassador of Savoy, lived in Château des Allymes. He was one of the main negotiators of the Lyon Treaty, which was signed in 1601. Negotiations took place in Lyon, the capital of the Gauls, after which the regions of Bresse, Bugey, Valromey and Pays de Gex were ceded to Henri IV and the Kingdom of France.

Château des Allymes then and now

A military fortress, perched in the first foothills of the Bugey mountains, the castle has stood tall above the Ain plains for more than 700 years. The tower, castle keep and curtain walls are a reminder of the internal fighting that took place between the Dauphiné and Savoy regions. The site was listed as a Historic Monument in 1960 and, in addition to a tour of the castle, the fort also proposes a rich cultural season of events every year, including concerts, conferences and exhibitions.
