Hermitage Museum
Its collections, of which only a small part is on permanent display, comprise over three million items (the numismatic collection accounts for about one-third of them), including the largest collection of paintings in the world. The collections occupy a large complex of six historic buildings along Palace Embankment, including the Winter Palace, a former residence of Russian emperors. Apart from them, the Menshikov Palace, Museum of Porcelain, Storage Facility at Staraya Derevnya, and the eastern wing of the General Staff Building are also part of the museum. The museum has several exhibition centers abroad. The Hermitage is a federal state property. Since July 1992, the director of the museum has been Mikhail Piotrovsky.
Gerard ter Borch
Ter Borch's works are comparatively rare; about eighty have been catalogued. Six of these are at the Hermitage, six at the Berlin Museum, five at the Louvre, four at the Dresden Museum, three at the Getty Center, and two at the Wallace Collection.
