Across Europe, churches and other Christian religious buildings stand increasingly empty. These empty churches are being repurposed. That means they are being changed into other things like hotels, sport climbing businesses, and even dance places. Supporters say the changes remove the need for costly repairs and care of the buildings. But critics say such changes raise ethical concerns. Empty churches can be seen over much of Europe - from Germany to Italy and many nations in between. But the empty churches really stand out in Flanders, in the northern part of Belgium. The area has some of the greatest cathedrals in Europe. Yet there are not enough people attending the churches. In 2018, the PEW research group released an opinion study of religion in Belgium. The study found that 83 percent of people said they had been raised as Christians. But only 55 percent still consider themselves to be Christians. And only 10 percent of Belgians still attend church regularly.
