By request of the inhabitants, the western area of Sihl/Limmat had been separated from Wiedikon area in the year 1787. This separation was perceived to be a gain and relief, which was also reflected by the illustration of an anchor in the coat of arms. The new district had been compared with a silver field where the black anchor, firmly connected to the ground, provides safety.
The district 4, known for its busy ambience and nightlife, has improved its order and safety massively with the wide-ranging undertaking „Langstrasse Plus“ as well as with the urban revaluation. Today not only young academics, artists and students explore the district 4 as a living space, which leads to broad cultural mix within the population. Thus, the attractiveness of the district as a trendy urban living area with historic buildings and very modern new constructions is increasing continuously.
