The former summer cottages of S. A. Muromtsev and N. P. Bakhrushin were transformed into an elementary and a high school called “Vlasovka” and “Bakhrushinka” after the names of their former owners.
During the German-Soviet War the area was heavily bombed by the German air force because of the proximity of the largest urban grain elevator.
In 1979 the house was declared uninhabitable because of dilapidation[4] and handed over to the Institute of Clinical and Experimental Medicine (Russian: Институт клинической и экспериментальной медицины (ИКЭМ СО АМН) “to accommodate special equipment” for a period of five years, after which the demolition of the building and improvement of the area was foreseen by the Soviet Academy of Medical Sciences.

In recent decades a museum was established in the dacha, dedicated to the memory of the several outstanding people who various times visited Tsaritsino or lived here during the past century.
The museum housed the meetings of the veterans of Tsaritsyno, arranged puppet shows for children, student seminars, evenings for the association of families with many children, public readings of contemporary literature, and collective screenings of contemporary Russian animated films organized by “Nike” laureate director Ivan Maximov.
On 15 May 2009 the representatives of the Social Movement “Arkhnadzor” Y. V. Mezentseva and K. P. Mikhailov in the legally required way presented an application for the recognition of “the dachas of old Tsaritsyno, linked between 1900 and 1970 to the name prominent national historical and cultural figures S. A. Muromtsev, I.
