The three men are working together to build a common house of worship — the "House of One" — in the center of the capital that will include a church, a mosque and a synagogue, as well as a joint meeting hall at the center of the building. The central meeting hall will be able to seat 380 people, with the separate church, synagogue and mosque all adjacent to it. In an online crowd-funding campaign, the three clerics are asking people from around the world to contribute by buying bricks for the building for 10 euros ($13.40) each. Since launching the campaign at the start of June they have received a little more than 35,000 euros ($46,800). The three are also seeking corporate sponsorship and larger donations from private individuals, and the plan is to start construction work in 2016.
