The mansion on Pesochnaya Embankment, which now houses the Leonard Euler International Mathematical Institute of the Russian Academy of Sciences, was built in 1913-1914 according to the project of architect Nikolai Lansere.
In the 1850s, the estate of captain A.E. Engelhardt, son of the director of the Imperial Tsarskoye Selo Lyceum. In the depths of the garden, which departed inland from the coast of Malaya Nevka, there was a wooden cottage behind it - a utility yard, a vegetable garden and a greenhouse.
In the early 1860s, the wife of an honorary citizen V.A.Novinskaya became the owner of the estate, at the beginning of the XX century it was inherited by granddaughters - M.A. Novinskaya and V.A. Zasetskaya. For them, a two-story stone mansion in the neoclassical style was erected. Each of the sisters occupied a separate floor with a separate set of premises. Only the kitchen block was common.
The main facade of the mansion is decorated with two protruding risalits, the western wing in the courtyard is very advanced - it housed an economic unit and premises for servants. The central part of the facade facing the river is highlighted by an order with Corinthian columns. The eastern facade is decorated with a half-tonde of Tuscan order. To the south of the mansion is a glacier decorated with a portico.
In the Soviet years, the mansion was occupied by a tuberculosis dispensary. In the 1990s, the building was restored, historical interiors were recreated.
