Brunnenturm, Fortified tower in Old Town Zürich, Switzerland

Brunnenturm is a fortified tower with a square base and tent-shaped roof standing in Zurich's Old Town. The building now houses a parent education center and daycare facility run by the city's school department.

The tower and its adjoining hall were built around 1250. From 1357 to 1429 it belonged to Lombard merchants and moneylenders, hence the name Kawertschenturm. In 1429 Thoman Velleti sold it to Götz Escher, whose family held it until 1810. From 1810 it housed a private school, then institutions for the blind and deaf, and from 1879 a public and vocational school.

The tower gets its name from a fountain that once stood in front of it and shaped the square's character. Today visitors can read the story of medieval Zurich written in its stones.

The tower stands at the upper end of Napfplatz, where Napfgasse, Spiegelgasse and Obere Zäune meet, in front of the restaurant "Turm". The square and its fountain were moved in 1876, so the basin no longer sits directly before the tower. The building itself houses a city parent education centre and daycare and is not open as a museum.

The tower's name comes from the fountain built in front of it in 1567/68, which stood there for over three hundred years. In 1876 it was moved to the lower third of Napfplatz, and its damaged column and statue were removed. The old fountain column has been in the Swiss National Museum since 1910.
