Brest Fortress (Belarusian: Брэсцкая крэпасць, Brestskaya krepasts' ; Russian: Брестская крепость, Brestskaya krepost' ; Polish: Twierdza brzeska), formerly known as Brest-Litovsk Fortress, is a 19th-century Russian fortress in Brest, Belarus. It is one of the most important Soviet World War II war monuments commemorating the Soviet resistance against the German invasion on June 22, 1941 (Operation Barbarossa). Following the war, in 1965 the title Hero-Fortress was given to the Fortress to commemorate the defence of the frontier stronghold during the first weeks of the German-Soviet War. It was then part of the Byelorussian SSR. The title Hero-Fortress corresponds to the title Hero City, that was awarded to an eventual total of twelve Soviet cities. Brest Fortress is situated at an height of 135 meters.[1]
