What Château de Chapeau Cornu does

Château de Chapeau Cornu is a privately held French hospitality company (legal entity CHATEAU CHAPEAU CORNU, SIREN 387465354, registered capital €24,000) operating a 13th century medieval castle property in Vignieu, Isère, Auvergne-Rhône-Alpes, approximately 45 minutes from Lyon and one hour from Grenoble. The integrated estate runs a 4-star castle hotel with 13 rooms, a 1-star annex (Les Dépendances) with 31 rooms across Archers, Cavaliers, and Chevalier Suites categories, two restaurants (gastronomic Le Capella at a €135 signature menu and La Rôtisserie offering €19-25 lunch menus), and the Spa du Château which offers Cinq Mondes and Biovive wellness treatments together with a Glowzen Room bioluminescent relaxation experience launched in February 2020.

Revenue is generated across four streams: hotel accommodation paid per night across multiple tiers; restaurant service à la carte and banquet; spa and wellness bookings through the Planity platform at €38 per 2-hour access; and a large event-driven business comprising weddings (packages €3,900-€4,900, capacity 70-250 guests) and corporate seminars (250+ events per year, capacity up to 250 participants across 6-8 meeting rooms). Go-to-market combines direct website booking (Reservit platform), third-party booking (Secure-hotel-booking.com), restaurant reservations (GuestOnline), gift boxes (Secretbox), and venue discovery partnerships (Naboo), alongside a trilingual French/English/Chinese website and regional tourism board partnerships in Auvergne-Rhône-Alpes.

Customer segments are wedding couples and families, corporate groups for seminars and team building, leisure travelers and couples seeking romantic getaways and spa weekends, and celebration groups (bachelorette parties, birthdays). The 34-employee, founder/management-controlled operation under Thierry Regnier as Director of Publication and Legal Representative has run the hotel for approximately 20 years and is recognized by Zankyou as the second best castle in France for weddings. Pricing instruments include a corporate overnight stop package at €120 per person, significant advance-booking wedding discounts (up to €10,000 for 2027 weddings), and seasonal menu variation, reflecting a strategy that balances premium positioning with demand smoothing across the calendar year.
