 Both façades were again repainted in the Rococo style by Rudolf von Steiger in 1890 . The idealising historicism of the design came to be disliked in the 20th century , and a 1929 competition produced the façade designs visible today : on the west façade , Victor <unk> 's fresco " Beginning of Time " and on the east façade , a reconstruction of the 1770 design by Kurt <unk> . In 1981 – 83 , the Zytglogge was thoroughly renovated again and generally restored to its 1770 appearance . In the advent season and from Easter until the end of October , it is illuminated after dusk .
