and invited Werner March, architect of the Berlin stadium, to visit Belgrade and design objects for the games. March came to Belgrade in May 1938 and suggested the Fortress' Lower Town as the location for the Olympic complex. Without architectural design competition or bidding, Stojadinović's government accepted his idea and gave him carte blanche regarding the design. The project was finished in 1939 and the architectural model was exhibited in October 1940 at the "Exhibition of the new German architecture" in the German pavilion at the Belgrade Fair. In the early 1940, March began the preparatory works, as he also planned the partial remodeling of the fortress outside of the sports complex, too. He incited archaeological survey and invited German architectural historian Daniel Krencker to study the excavations. Within the scopes of the Nazi expansion of the megaprojects, and augmentation of the German historic role and importance in this region, Krencker praised March's project as the "artistic dream, which represents rare and major German cultural act which will contribute to the old German glory of Belgrade". Just few days after German scientists left the fortress, Germany attacked Yugoslavia on 6 April 1941. Olympic complex was pushed aside, shifting the focus of the Germans to the archaeological exploration of the fortress during the war. The fortress suffered further damage during World War II. Military Museum was damaged in the April 1941 bombing, and subsequently looted. It was immediately placed under the authority of the German Military Museums Chief. repaired, and reopened for public in July 1941. After almost two millennia of continuous sieges, battles and conquests, the fortress is today known as the Belgrade Fortress. The present name of Kalemegdan Park derives from two Turkish words, kale (fortress) and meydan (field), literally meaning "fortress field". After World War II, before skiing facilities were built on the mountains further from Belgrade, the slopes of Kalemegdan (so as of Banovo Brdo, Košutnjak and Avala), were used by Belgraders for skiing. Also, immediately after the war, some parts of the fortress were closed for public. In some parts the new, Yugoslav People's Army was stationed, while others were closed because of the ammunition left behind. In 2018 it was announced that the entire riverbanks section from the Branko's Bridge on the Sava, to the Pančevo Bridge on the Danube, will be transformed into the linear park, patterned after the High Line park in New
