Marysieńka Palace

You don’t have to stay overnight in a castle to feel its magic. Day SPA at Gniew Castle is an offer for residents of the Pomeranian region and everyone looking for an exceptional one-day spa experience – without booking a room. Swimming pools, saunas, a jacuzzi and original SPA rituals of Queen Marysieńka await in the underground chambers of one of the most beautiful castles in Pomerania.

Day Spa offers the opportunity to enjoy the Wellness and SPA zone of Queen Marysieńka without the need to stay overnight at the hotel. As part of the package, you get access to the wellness area – pool, saunas, and jacuzzi – as well as a selected treatment or massage, surrounded by an atmosphere you won’t find anywhere else in the region: the historic brick walls of Gniew Castle.

If you are looking for a Day SPA in Pomerania or wondering where to spend a day at the spa without planning a whole weekend getaway, Gniew Castle is one of the few options in the region combining SPA treatments with a historic atmosphere. The formula was created with the residents of Pomerania and Kociewie in mind, who are looking for a unique idea for a free day, a gift for a loved one, or a moment of relaxation.
