Всеволожский район
Beloostrov historically consists of two parts: Novy Beloostrov (, "New White Island"; ) along the railway and Stary Beloostrov (, "Old White Island"; ) several kilometers to the north, mostly belonging to Vsevolozhsky District of Leningrad Oblast under the name Sadovodstva (). Until the Winter War Beloostrov was the last railway station before the Russia–Finland border.
