The Alte Pinakothek is one of the most important art galleries in the world. It presents over 700 works of European painting from the 14th to 18th centuries, including one of the largest collections of paintings by Albrecht Dürer and Peter Paul Rubens. The outstanding painters of all schools are represented by numerous major works, such as Rogier van der Weyden and Memling, Altdorfer and Cranach, Jan Brueghel the Elder and van Dyck, Raphael and Titian, Rembrandt and Frans Hals, Poussin and Murillo. The rich art treasures of the Wittelsbach family form the core of the collection. The Alte Pinakothek, commissioned by Ludwig I of Bavaria, was opened in 1836. The architect Leo von Klenze designed a groundbreaking museum building whose large halls are illuminated by natural skylights. The Alte Pinakothek was considerably destroyed during the Second World War, and thanks to the saving efforts of Hans Döllgast in the 1950s it became an exemplary reconstruction architecture. The Alte Pinakothek is located in the centre of the so-called Munich Kunstareal and is part of the Bavarian State Painting Collection the world's largest closed collection of paintings.
