The Palace at Osowa Sien is a privately owned 19th-century estate in western Poland, offered exclusively as a home for intimate, multi-day wedding celebrations.

Rather than a traditional venue, the palace is lived in over several days. Most weddings unfold over four to seven nights, allowing the estate to become your exclusive home — without the structure or restrictions of a hotel or event venue. Days and evenings flow naturally, with guests free to gather late into the night and make use of the house and grounds at their own pace. Time is spent not only inside the palace, but across the wider estate — from the park and terraces to bonfires after dark — creating a celebration shaped by time well spent together, rather than a hurried timetable.

Most celebrations host around 30–50 guests, with everyone staying on site. Shared meals, quiet mornings, long evenings, and time spent together under one roof foster an experience that feels deeply personal, immersive, and connected.

The house is privately hosted and carefully maintained, and intentionally free of rigid formats or required suppliers. Couples have full freedom to shape the celebration — from the flow of the days to how meals, shared moments, and gatherings unfold. Some choose to cook and dine together, others bring in trusted catering teams, or opt for our signature hosted dinner experience, a farm-to-table feast arranged in the ballroom. Optional elements such as floral design, planning support, massages, or a fully stocked pantry with seasonal local produce can be thoughtfully arranged, while the house itself remains at the centre of the celebration.
