The hotel we stayed in had a very large war memorial on the roundabout outside called the Monument to the Defenders of Leningrad. It's a huge panoramic monument with an underground museum which documents the 900-day siege of Leningrad which took place between 8th September 1941 and 27th January 1944 when German troops surrounded the city. It's a very impressive monument and you can find monuments to World War II like this everywhere you travel in Russia.
