Lehmbruck Museum is devoted for Wilhelm Lehmbruck (1881-1919) and his sculptures make up a large part of its collection. However, the museum has a substantial amount of works by other 20th-century sculptors, including Ernst Barlach, Käthe Kollwitz, Ludwig Kasper, Hermann Blumenthal, Alexander Archipenko, Raymond Duchamp-Villon, Henri Laurens, Jacques Lipchitz, Alexander Rodtschenko, Laszlo Péri, Naum Gabo, Antoine Pevsner, Pablo Picasso, Salvador Dalíand Max Ernst. This is complemented by a considerable number of paintings by 19th- and 20th-century German artists. The museum circulates its substantial collection by re-installing works on an annual basis.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
