 The city then declined until the arrival of the railway in the 19th century, and with its industrialisation into the 20th century.The old town is made up of a variety of historic houses, palaces, churches, plazas, avenues and parks, and includes the National Museum of Sculpture, the Museum of Contemporary Art Patio Herreriano or the Oriental Museum, as well as the houses of Zorrilla and Cervantes which are open as museums.Among the events that are held each year in the city are the famous Holy Week, Valladolid International Film Festival (Seminci), and the Festival of Theatre and Street Arts (TAC).
