The Russian Monument (Bulgarian: Руски паметник, Ruski pametnik) is a monument in Sofia, the capital of Bulgaria. The first monument to be built in the capital of the newly liberated Principality of Bulgaria, it was unveiled on 29 June 1882 and is located on the road which Osman Nuri Paşa used to flee from Sofia to Pernik on 22 December 1877. The funds for the construction of the memorial were collected by the Russian people. It is not exactly known who designed the monument, but it is supposed to be either the architect Vokar, who designed such monuments in Dobrich, Pleven Razgrad, Veliko Tarnovo, Svishtov, or Vladimir Sherwood, who worked in Pleven.
