A Christian, a Jew and a Muslim walk into the same house of worship...

IT IS USUALLY bad news when multiple religions claim the same place of worship. It can lead to conflict, as illustrated by the recent violence at Jerusalem’s holiest site. Or it can be a sign that flocks are dwindling, forcing congregations to share space. But Berlin’s House of One intentionally puts a church, mosque and synagogue under a single roof.The cornerstone of the €47m ($57m) place of worship was laid last week near Alexanderplatz. In four years’ time, it will be a structure housing three separate prayer rooms and a 46m-high domed hall for the faiths to mix. “We are building the House to make a statement,” says Rabbi Andreas Nachama, one of the project’s leaders.
