St. Peter is one of the four main churches of the old town of Zürich, Switzerland, besides Grossmünster, Fraumünster and Predigerkirche.

Prior to the Reformation, St. Peter was the only parish church of the town, the rest being part of monasteries.

The first reformed pastor, Leo Jud (1523–1542), was a friend of Huldrych Zwingli and contributed to the first translation of the Bible in Zurich.

Belfry and bells belong to the Reformed Church of the canton of Zürich, as well as the staircase leading to the tower.

In 1450 the tower was increased to 64 metres (210 ft) (as of today) and a pitched (helmet) roof was attached.

That 24-metre (79 ft) high part of the tower was in 1996 re-covered with 42,000 larch shingles from the Engadine valley,[1] since then being the only wooden roof in Zürich.

[3] Around the 1st century BC La Tène culture, archaeologists excavated individual and aerial finds of the Celtic-Helvetii oppidum Lindenhof, whose remains were discovered in archaeological campaigns in the years 1989, 1997, 2004 and 2007 on Lindenhof, Münsterhof and Rennweg-Augustinergasse,[4] and also in the 1900s, but the finds mistakenly were identified as Roman objects.

Not yet archaeological proven but suggested by the historians, as well for the first construction of the today's Münsterbrücke Limmat crossing, the present Weinplatz square was the former civilian harbour of the Celtic-Roman Turicum.
