The sale of church buildings has become commonplace in France – but a recent proposal to convert a church to a mosque has triggered a nationwide controversy. Church congregations in France are dwindling and the town of Vierzon is no exception. With a population of only 27,000, Vierzon is home to six Roman Catholic churches. To balance its books, the local diocese decided to sell one of the churches. But tempers flared after a Moroccan Muslim organization said it wanted to buy the church and convert it to a mosque.
