Berlin has a unique plan to build "House of One", the world's first house of prayer for the three big monotheistic religions – Islam, Christianity and Judaism, aiming to bring them together under one roof, reports Deutsche Welle.
The house of worship is being built in Berlin of Germany, containing a mosque, a church and a synagogue, where a priest, an imam and a rabbi will pray right next to each other.
A piazza with a roof on top will also serve as a meeting ground for them and their communities.
Worshippers and members of the public can come together and learn more about the religions and each other.
The open space is already visible as a model where "multi-religious meditations" are already taking place in this provisional wooden construction that could be seen from a distance, according to Deutsche Welle report.
In the past, different faiths have used the same buildings but not usually at the same period.
Mosques in southern Spain became cathedrals after the Christian conquest.
In Turkey, churches became mosques. In Britain old Welsh chapels have sometimes become mosques as areas change - and Brick Lane mosque in the East End of London started as a church in the 18th Century, later became a synagogue before turning to Islam, and has now become a place of worship for the newly arrived Muslim community.
But that's different from the three faiths worshipping as neighbours under one roof.
The idea came from the Christian side of the triangle.
It will be built where the first church in Berlin, dating back to the 12th Century, was once situated. St Petri's Church was badly damaged at the end of World War-2 as the Red Army liberated Berlin. What remained was destroyed in the period after the war by the East German authorities, reports BBC.
Then, six years ago, archaeologists uncovered remains from an ancient graveyard and it was decided that something should be done to resurrect a community and its place of worship.
The project expanded and changed from a single-faith building to the present three-faith plan.
Now, Money is being raised to turn the plan into bricks and mortar.
