Map - Wangen bei Olten (Wangen bei Olten)

Wangen bei Olten is a municipality in the district of Olten in the canton of Solothurn in Switzerland.

The construction of a six-meter (20 ft) high minaret in Wangen in 2005 led to a constitutional ban on their construction on 29 November 2009.

The contention involved the Turkish cultural association, which applied for a construction permit to erect a minaret on the roof of its Islamic community centre. The project faced opposition from surrounding residents, who formed a group to prevent the tower's erection. The Turkish association claimed that the building authorities improperly and arbitrarily delayed its building application. They also believed that the members of the local opposition group were motivated by religious bias. The Communal Building and Planning Commission rejected the association's application. The applicants appealed to the Building and Justice Department, which reverted the decision and remanded. As a consequence of that decision, local residents (who were members of the group mentioned) and the commune of Wangen brought the case before the Administrative Court of the Canton of Solothurn, but failed with their claims. On appeal the Federal Supreme Court affirmed the decision of the lower court. The minaret was eventually erected in July 2009.

While the case led to a ban on further minaret construction, it did not affect the four minarets already then in existence in Switzerland, including that of Wangen bei Olten.
