The Museum of Warmia and Mazury in Olsztyn is more than just an exhibition space; it is the living heart of the cultural heritage of northern Poland. The museum's main residence is housed in a majestic 14th-century Gothic castle, which is considered the oldest surviving building in the city. This architectural masterpiece, built for the administrators of the Warmian Chapter, impresses with its austere beauty and powerful walls that have witnessed many historical events.

Inside the museum, guests can immerse themselves in the atmosphere of past eras through extensive collections of archaeological finds, decorative arts, and ancient icons. Of particular value is the art collection, reflecting the spirit and traditions of the Warmia and Mazury region. Situated in a picturesque location where the Łyna River makes a sharp bend, the castle serves as an ideal starting point for exploring the history of Olsztyn.
One of the museum's greatest treasures is a unique astronomical artifact associated with the great scientist Nicolaus Copernicus. The castle not only preserves memories of the past but also actively lives in the present, offering visitors a modern perspective on the traditional culture and art of the Mazury region through innovative programs and temporary exhibitions.
