A self-catered castle in western Poland, set among centuries-old trees and white historic walls. The Palace at Osowa Sien is a fully private home for families, friends, and groups who value space, privacy, and time together. Just a two-hour flight from major UK airports to Poznań or Wrocław, with multiple direct arrivals daily, and within easy driving distance of Berlin, the estate is simple to reach — yet quietly removed from everyday life.
The Palace at Osowa Sien is not a hotel, and not a traditional event venue. It is a private castle home, reserved entirely for your group. Each stay is shaped around how you want to live in the space — from guest room layouts and bed configurations, to self-catered living, to a small selection of thoughtful services that add comfort without intruding on privacy. From first contact to departure, our role is straightforward: to make your stay effortless, restorative, and genuinely inspiring.
The castle offers twelve individually styled suites, alongside generous rooms designed for both togetherness and retreat. Historic architecture is balanced with warmth and comfort, so the spaces feel lived-in rather than formal. A large kitchen supports shared cooking and long meals, while the dining room seats all overnight guests with ease. Salons shift naturally between quiet reading, conversation, working sessions, and evenings by the fire. And when celebrations unfold, there is a ballroom with a dance floor and disco ball — for nights that are meant to dazzle.
Set in western Poland, Osowa Sien is well positioned for guests arriving from across Europe, the UK, and beyond. Berlin is an easy drive away, and both Poznań and Wrocław airports offer frequent direct connections from London, Manchester, Birmingham, Edinburgh, and other UK cities, as well as links via major European hubs and the United States.
This experience suits people who want something more personal than a standard hotel stay. Families gathering across generations, friends marking milestones, intimate wedding groups, retreat hosts, and creative or business teams value the freedom, privacy, and flexibility the castle provides. The setting adapts to your pace — not the other way around.
Plush blankets, flickering candles, and the soft crackle of the fireplace invite relaxation; here, comfort isn’t just an idea—it’s the essence of your stay, ensuring you and yours unwind into the tranquility of an unhurried, private escape.
Mornings tend to unfold slowly, with breakfast in sunlit rooms and no need to rush. Evenings gather naturally around the fireplace, bonfires, or long tables. You may choose complete self-catered independence, or complement your stay with selected services such as pantry stocking with local produce, massages using honey, herbs, and oils sourced nearby, or bespoke experiences arranged to suit your plans. Hospitality here is quiet and personal, shaped around how you want to spend your time.
Availability is limited by design to ensure full privacy for each group. We recommend checking dates early and reserving your stay in advance. Contact us directly for availability and a tailored quote.
