Graz has had a long-standing cultural significance, despite a relatively short-lived political heyday, and art and culture continue to set the tone in this city. The lanes and streets of the old-town echo with the culture of the Middle Ages. The original town centre, nestled at the foot of the Schlossberg with its famous Clock Tower, has been a repository of the architectural styles of each era, from Gothic, Renaissance and Baroque through to modern styles.
