Irchelpark

Irchelpark is the biggest public park in the city of Zürich in Switzerland, and claims to be the most spacious park in Switzerland.

Location
Irchelpark is situated mainly in Zürich-Unterstrass, a district of the city of Zürich. The area also houses the Irchelpark faculty of the University of Zürich and is one of the largest public parks in Zürich. Public transport is provided by the Zürich Tram routes 7, 9, 10 and 14, as well by the VBZ bus lines 39, 69, 72 and 83 at the Milchbuck hub.

The park is divided by the Winterthurerstrasse respectively by one of the feeders of the A1 motorway in two different sites, bridged by a wide natural stone stair, of which the lower part af the park is partially situated. The upper part houses the university's campus, as well as underground sports, former military (Zivilschutz) and parking facilities, and the structures of the Staatsarchiv Zürich. A further extension of the Staatsarchiv building was approved by the parliament of the Canton of Zürich in March 2016 for the construction of Bau 3 (stage 3) for 25 million Swiss Francs; adjacent to the present building (stage 2), a cafeteria and conference rooms will be built, including a solar power plant. Because the capacities of the Irchel campus of the University of Zürich also are exhausted, an extension was started in mid-April 2016 to be also completed in 2019. Phase 5 comprises three further campus buildings of 14000 m2 for 195 million Swiss Francs.

History
In 1962, the faculty of science of the University of Zürich proposed to several university institutes, to improve the utilization of synergies and cost savings in a campus on the Strickhofareal that is situated at the western slope of the Zürichberg hill. The first stage of the construction works of the university buildings begun in 1973, and the campus was inaugurated in 1979. The construction of the second stage lasted from 1978 to 1983. Among other things, the excavated material of the first and second stage was a problem that was not solved, thus the terrain in the Unterstrass and Oberstrass district was used for landfills. On the basis of the adjusted goals, a competition for the design of a park was started in 1979.

Geography and structure
As a first step in the lower part of the park was created with the artificial lake that is a separated by a wooden construction serving as pathway and a wide bridge crossing the water. The upper part houses the central axis of the campus towards Frohburgstrasse, where among others a restaurant, a wide meadow, and a scenic outpost overlooking the Limmat Valley are located. The then-new type of integration of gaming activities, a jogging facility, natural playgrounds and fireplaces in the natural areas of the park harbored a certain risk but were solved within the 1990s.

Safety
In 2010 there have been several cases of physical attack and harassment at Irchelpark after nightfall. Although the safety problem are still not completely resolved, there are no surveillance cameras installed in the park, and the University of Zürich publishes recommendations for the students who use the park at night to access the public transport stops from campus.
