The last owner of Łańcut, Alfred Antoni Potocki, (14 June 1886 – 30 March 1958), was one of the richest men in prewar Poland, accumulating a fantastic collection of art during his tenancy. Shortly before the arrival of the Red Army in 1944, he loaded 11 railway carriages of a specially chartered train to Vienna, with his most valuable possessions (about 700 boxes of movable property) and fled to Liechtenstein. Most of these valuables were gradually sold off to finance a lavish lifestyle.
