St Peter's is the oldest church in Zurich. It stands in a small square surrounded by houses and shops but its impressive spire dominates the city. St Peter's Church, also known as St Peterskirche, is so tall that from the Middle Ages until the early 20th century it was used by the night-watch keeping an eye out for fires breaking out in the city. On this spire is the largest church clockface in Europe with a diameter of 28.5 ft (8.7 m). The minute hand is 12 ft (4 m) long!
The Peterskirche was first built in the 9th century, but was altered in the 13th century and again in the 17th century. The interior is plain, white with wooden columns and pews but in the choir the remains of a medieval mural can be seen.
