Before the German-Polish borders changed in 1945, a vivacious Leonie Ossowski (then Jolanthe von Brandenstein) grew up inside these very palace walls. As luck would have it, she became an accomplished author known for her engaging depictions of Osowa Sien and life at her family’s castle - later reimagined through her Silesian Trilogy and definitive literary works.

As an homage to her and the happenings that once characterised this countryside village, our collection of suites have been inspired by her riveting books.

Each guest quarter shown below comes equipped with highspeed WiFi, TV, ensuite bathrooms with imported stone floors (and sporting both a walk-in shower and a separate bathtub), organic toiletries (soap, shampoo, conditioner, hand cream), all-natural and ethical coffee and tea provisions (from the hand-roasters at G-Coffee and the suitably British Tea Pigs respectively), kitchen annex or pantry, private seating area, and heated Floors.
