Ferrette fortress, in Alsace, is 612 metres at its highest point. It's ruined, nowadays, but a manuscript described the castle as it was in the Middle-Ages: we found three main buildings:
• the Oberschloss ("Upper building"), with 11 rooms, kitchens, steam room and cellar. Also, we found a well and a chapel dedicated to Sainte-Catherine.
• the Bailiff's house, with 7 rooms, two kitchens, a stable for three horses and vast cellars;
• Knight's dwelling, with a room flanked by cellars.
The first mention of the castle dates back to 1104, with Frederic I: the man inherited Ferrette's land from his father, count of Montbéliard; he and his descendants will take later the name of Ferrette. Frederic raised the keep on the foundations of a tower put up by Romans. In 1324, the castle fell to the House of Austria, when Jeanne de Ferrette married one Hapsburg guy.
Then emperors Maximilian I and Maximilian II reinforced the fortifications. Ferrette was demolished and burnt by the Swedish during the Thirty Years War. The surrounding wall was preserved from the fire but all the other buildings had to be rebuilt...
