The museum was built on the 100th anniversary of the liberation of Pleven from Ottoman rule. It shows the siege of the city from July 20 to December 10, 1877, during which four main battles took place, the third of which played a key role in the Russo-Turkish war that ended with the liberation of Bulgaria.
In the first room, you can see 6 paintings depicting, among others the April Uprising, the passage of Russian troops across the Danube and the Ottoman yoke. The main panorama is 115 meters long and 15 meters high, and its diameter is 40 meters. It shows the bloodiest battle for Pleven, which was fought on September 11-12, 1811. Visitors can see it from the center of the battlefield.
In the last rooms there is a smaller diorama depicting the last Battle of Pleven and two paintings showing the surrender of Osman Pasha and the march of the Russian army through the Balkans. There are also two observation decks on the roof of the museum, which can be reached by elevator.
