Exceptional 12th-Century Medieval Castle – Picardy, France Located 15 km from Soissons, this remarkable historic monument combines nearly nine centuries of history with an outstanding restoration. Built around 1138 and transformed into a 22-metre cylindrical keep in the 14th century, it was once owned by La Hire, companion-in-arms of Joan of Arc. Acquired in ruins in 1980, the castle was carefully restored, blending medieval authenticity with contemporary architecture. Its impressive features include four vaulted levels, a historic staircase, fortified walls, defensive towers and chapel ruins. Until recently, the estate operated seven prestigious five-star apartments. This rare property offers exceptional potential as a private residence, luxury hospitality venue, cultural destination or heritage investment, just 1.5 hours from Paris.
