The Waisenhaus building is situated at Bahnhofquai 3 towards Bahnhofbrücke and Hautbahnhof Zürich. Built in fact outside of the historical core of the medieval town of Zürich, previously the Celtic-Roman Turicum, the former Zucht- und Waisenhaus is the last remaining structure of the Oetenbach nunnery at the Lindenhof-Silhlbühl hill on the western shore of the Limmat river.
After the Reformation in Zürich, the city government took over the monastic buildings for new uses. To manage the income of the former convent, the former administration building was held as Oetenbacheramt housing the former wine cellar. In 1601 the building was extensively remodeled and equipped with stepped gables, and as police barracks, in 1872 the remains of wall paintings were discovered. After a renovation in 1735 the south facade was in 1776 redesigned with a simple baroque, and an additional ceiling was set up and a second floor. From 1799 to 1802 the church buildings were among others used as a military hospital. Already between 1637 and 1639 the ground floor was used as an orphanage in the north, in the west wing a prison was set up in the former dormitories of the nuns. In 1771 the orphans were held in the newly built orphanage in the former monastery's garden, and the north and west wings were extensively needed to be rebuilt as a penitentiary and workhouse, separating the prison from the new orphanage. The former orphanage today serves as the official Stadthaus I at the present Waisenhausstrasse, meaning orphanage lane. When the remaining buildings of the Oetenbach nunnery were broken, the occasion was not used by the archaeologists to secure finds of the Oppidum Zürich-Lindenhof. In 1903 the adjoint Oetenbachbollwerk bastion was broken as the last structure of the city's fortifications. The subsequent so-called Gedecktes Brüggli served as a pedestrian bridge, and was broken in 1953.
The buildings was rebuilt for a last time between 1868 and 1878, and probably the present Giacometti entrance area in 1890, and the last original structures of the Oetenbach nunnery may have been removed by as original 1901 plans by Ferdinand Curti and Hermann Fietz suggest. The lack of space and the separation of prisoners by criminal categories ordered by the then new criminal law, initiated the design and construction of a new detention center for modern principles, and so in the night of 8 to 9 October 1901, the prisoners were moved to the new prison Pöschwies in Regensdorf. In the same year, the remaining monastery area passed into the possession of the city of Zürich. The remaining Oetenbach building were broken in 1901/02, but the Waisenhaus, meaning orphanage, was preserved in favor of an administrative center, that in 1904/1905 took place at the former Sihlbühl which then was separated by the easterly Uraniastrasse and the building complex housing the Urania Sternwarte.
The building remained unused until 1911, and when the Stadthaus was rebuilt and the neighbouring Amthaus buildings were erected by Gustav Gull it became the present headquarters of the police department of the city of Zürich, meaning in German Stadtpolizei Zürich.
Gustav Gull integrated the Stadhaus building between 1911 and 1914 in the Urania complex, and the former cellar at the entrance floor of the Waisenhaus building was redesigned on behalf of Emil Klöti by Augusto Giacometti between 1923 and 1925 with vault and wall paintings, which are considered as a work of art of national importance. On occasion of the total renovation of the office building, the so-called Giacometti Halle was extensively renovated from 1985 to 2000.
Cultural heritage of national importance
