At the end of the 18th century an impressive collection of the Duke of Courland Peter von Biron (1724-1800), counting several hundred works of art, was moved to Silesia. At the time it was mostly stored and exhibited in the palace in Sagan. The second daughter of Peter von Biron, Paulina (1782-1845), married Friedrich Hermann von Hohenzollern-Hechingen who resided in Löwenberg (today's Lwówek Śląski). After the wedding, which happened soon after her father's death, she moved into her husband's residence, together with the part of her father's art collection which she inherited.
The part of the collection moved from Sagan to Löwenberg featured among others works by Rembrandt, Jan Steen, Meindert Hobbema, Jan van Goyen and Emanuel de Witte. The catalogues of Löwenberg's collection list over 400 paintings, including works by David Teniers, Salvatore Rosa, Jacob van Ruisdael, Gerard ter Borch, Andrea Mantegna, Pietro Perugino and Domenico Ghirlandaio.
