 Between 1918 and 1944, it was known as Uritsky Square (), in memory of the assassinated leader of the city's Cheka branch, Moisei Uritsky.The earliest and most celebrated building on the square, the Baroque white-and-turquoise Winter Palace (as re-built between 1754 and 1762) of the Russian tsars, gives the square its name.Although the adjacent buildings are designed in the Neoclassical style, they perfectly match the palace in their scale, rhythm, and monumentality.
