 Once the bolsheviks had taken power in Dnipropetrovsk the city was gradually purged of tsarist-era monuments and monumental architecture was stripped of Imperial coats of arms and other non-socialist symbolism.In 1917, a monument to Catherine the Great that stood in front of the Mining Institute was replaced with one of Russian academic Mikhail Lomonosov.Later, due to damage from the Second World War, a number of large buildings were reconstructed.
