Mosques anchor Muslim communities, but also act as lightning rods for resentment and suspicion. The Swiss, for example, voted in a 2009 referendum to ban the construction of minarets. (Most mosques have at least one, but the Quran doesn’t strictly require them.) The vote was overwhelming: over 57% of the population and 22 of the 26 cantons
approved it, despite opposition from the government, and an anti-minaret campaign poster explicitly linked mosque architecture with terrorism.
