The oldest landmark in Solothurn is the clock tower. Zeitglockenturm has stood proudly in Marktplatz, the center of Old Town, since the 13th century. This beautiful astronomical clock, by Von Lorenz Liechti and Joachim Habrecht, was added in 1545. As its golden hands move around the painted Zodiac signs, it not only tells the hour and minutes but also the day, month and year.
