In 1963, the Prague City Gallery was officially put in charge of the management of the collection of public space sculpture owned by the City of Prague. The gallery has since then taken systematic care of the sculpture in its charge, performing both routine upkeep and maintenance duties, as well as managing large-scale restoration projects aimed at reinstating the original material and artistic values of works on public display. Apart from that, the department devotes part of its operation to work on exhibition projects. Of these, a medium-term exhibition entitled Stone Treasures from Prague Gardens is currently open to visitors in the cellars of Troja Château. The department is involved in organizing commented viewings for the general public, building up archives of documents relating to the collection of sculpture in its charge, and since 2019 participating in a programme under the motto Art for the City.
