The east wing of this magnificent building, wrapping around the south of Dvortsovaya pl and designed by Carlo Rossi in the 1820s, marries restored interiors with contemporary architecture to create a series of galleries displaying the Hermitage's amazing collection of Impressionist and post-Impressionist works. Contemporary art is here, too, often in temporary exhibitions by major artists.
Entry to the galleries is via a broad new marble staircase, which doubles as an amphitheatre for musical performances held in the glassed-over courtyard. At the time of research, installation of all the artworks was underway and should be completed by the end of 2015.
