Russian Trade & Industry Bank building, Bank building in Bolshaya Morskaya street, Saint Petersburg, Russia.

The Russian Trade & Industry Bank building at 15 Bolshaya Morskaya Street in Saint Petersburg was built in 1912–1914 to a design by Marian Peretyatkovich. Its lower floors are clad in rare Nyshtadt granite, with mascaron keystones carved by sculptors L. A. Ditrikh and V. V. Kozlov. A stone balustrade runs along the fourth floor, and the carved frieze shows male profiles, rams' heads, cartouches and armour.

A house stood on the site by the 1740s, owned by General P. V. Izmailov's family until 1788; the merchant Friedrich Amburger bought it in 1793. In 1910 the Russian Trade and Industry Bank held a competition won by 38-year-old Marian Peretyatkovich, and the new building rose between 1912 and 1914, among his last works before his death in 1916.

The carved frieze on the fourth floor carries male profiles, rams' heads, cartouches and armour, modelled by sculptors L. A. Ditrikh and V. V. Kozlov, who also made the masks on the keystones above the second-floor windows. The lower floors are faced in Nishtadt granite, rare in Saint Petersburg, cut with a point-tooled and rock-faced texture.

The entrance front faces Bolshaya Morskaya street at number 15, a short walk from Nevsky Prospect and close to Palace Square. The lower floors are clad in Nyland granite, so look at the carved masks on the keystones above the second-floor windows. The banking hall with its polished dark-pink rapakivi colonnade is a working interior, so access depends on the bank's opening hours.

The granite facing the lower floors is nishtadtskii granite, rare in Saint Petersburg, and the blocks are worked with a point texture and a rock-face finish. The masks on the keystones above the second-floor windows were modelled by sculptors L. A. Ditrikh and V. V. Kozlov and cut from the same stone.
