The architect Leo von Klenze originally planned the main entrance to the New Hermitage to be on the western side, facing onto the narrow passage between the Small Hermitage and his building. To add greater interest he concentrated two-thirds of all the external sculptural decoration on this façade. Eighteen sculptural depictions of artists and sculptors (including Zeuxis, Apelles, Polycleitus, Pheidias, Scopas, Michelangelo, Raphael, Leonardo da Vinci, Rembrandt and Adriaen van Ostade) are placed in niches and on corbels protruding from the wall. In the mid-19th century they indicated the location of the halls containing painting or sculpture belonging to one school or another. The life-sized statues were cast in an alloy of zinc from models by the Bavarian sculptor Johann Halbig. Later, when it was decided to put the main entrance on the Millionnaya Street side, six sculptures (of Marcantonio Raimondi, Onatas, Smilis, Johann Winckelmann, Daedalus and Raffaello Morghen) were placed in niches flanking the portico.
