Kupetz Eliseevs Shop

Elisseeff Emporium in St. Petersburg is a large retail and entertainment complex, including a famous food hall, constructed in 1902–1903 for the Elisseeff Brothers. Located at 56 Nevsky Prospekt, the complex consists of three buildings, although the corner one is the structure that is referred to as Elisseeff's store or shop. Designed by architect Gabriel Baranovskii, it is one of the most striking examples of St. Petersburg Art Nouveau architecture, although at the time of its construction the building was considered controversial.
