Since 1945 much of the city's architectural beauty has been restored. Among the historic buildings are the churches of St. Sebald (1225–73), St. Lorenz (13th–14th cent.), St. Jacob (14th cent.), and Our Lady (1352–61); the Hohenzollern castle (11th–16th cent.); the old city hall (1616–22); and the house (now a museum) where Albrecht Dürer lived from 1509 to 1528. A large portion of the city walls (14th–17th cent.) still stands. Nuremberg is the site of the German National Museum (founded 1852), a part of the Univ. of Erlangen-Nuremberg, and a museum of transportation.
