Lobkowicz Collections, o.p.s. is the non-profit entity which manages the Lobkowicz Collections, one of Europe’s oldest and finest private collections, comprised of items dating back over 2,000 years. Among tens of thousands of objects are outstanding fine and decorative arts, arms and armor, musical manuscripts, and a 65,000-volume rare books library, along with millions of archival documents—built upon centuries of patronage and stewardship. The Collections were confiscated under the Nazi and Communist regimes of the 20th century. With the passage of the Czechoslovak restitution laws in the early 1990s, the Lobkowicz family reclaimed and reassembled the Collections, making these previously hidden treasures fully available to the public for the first time in history. The Collections are currently exhibited at the Lobkowicz Palace in Prague Castle and Nelahozeves Castle.
