In the first half of the 20th century Natolin passed to the Branicki family. During World War II Natolin suffered further. At time of Warsaw Uprising it underwent an almost total destruction. In 1945 Natolin was nationalized and given to the Warsaw National Museum, later becoming the residence of President of Polish Republic. In 1991, decision was made to locate a branch of the College of Europe Natolin. As a result, funds became available to gradually restore the park and the palace. In the same year a part of the park (nearly 1 km²) was declared a nature reserve. Since 1994 it is the site of one of the two College of Europe campuses.
