 According to Calatrava, who consulted Archbishop Demetrios with regard to the liturgical and iconographical requirements of the interior, the church would be built of steel and concrete, but the exterior would be clad in stone.The ground blessing ceremony and symbolic laying of the cornerstone took place on October 18, 2014, attended by government and church leaders, with construction expected to be completed within two years.In September 2015 a live webcam showing the church's construction was made available.
