St. Peter’s Church is adorned with the largest clock face in Europe. Its circumference measures 28.5 feet. There are five bells dating from 1880 in the tower - the largest one weighs over six tons without its clapper.
From the Middle Ages until 1911, the church tower served as a fire lookout point.

St. Peter's is the oldest church in Zürich, and its origins go back to pre-900.
The city’s first mayor, Rudolf Brun, who was buried in 1360 in the choir of the church, acquired St. Peter's in 1345 with all the associated privileges (church tax) and obligations. He now has a grave and monument by the outer tower wall. The first reformed pastor, Leo Jud (1523-1542), was a friend of Zwingli and contributed to the first translation of the Bible in Zürich. J.C. Lavater (writer, physiognomist, friend of the young Goethe) was pastor from 1778-1801. His gravestone can be seen in the church wall, and there is a memorial to him in the church choir.
