This museum was opened in 1983 on the 40th anniversary of the liberation of Oryol and is dedicated to the Oryol Offensive Operation of the Second World War which is also known as the Kutuzov Operation. The most striking feature of the museum is its 9 by 33 metre diorama which depicts the events of a battle on 12 July 1943 when the Soviets began to break the Nazi defences which would eventually result in the liberation of several Soviet cities including Oryol. The museum is run as a branch of the Regional Museum.
