One of the most notable landmarks in Graz and a must for any visitor, the Graz Clock Tower (Grazer Uhrturm) may be best known for its confusing clock faces, featuring long hands for the hours and short hands for the minutes. Dating back to medieval times, the tower stands 28 meters high and has a clock face on each side, each about five meters in diameter. The 18th century clockworks still operate, but are now electronic. In addition to the famous clock, the tower is also home to three bells, the oldest of which dates back to 1385 and still rings on the hour. Another bell from around 1450 was used during executions and later to remind people of the city curfew.

Once used to watch for fires in the surrounding area, the tower today offers visitors 360 degree views of Graz and its environs. Visitors should also look for the three painted coats of arms on the walls of the tower and the walled-in stone armchairs that were added in the 16th century.
