The Church of all Nations, also known as the Basilica of the Agony, lies on the foundations of two earlier churches: a 12th-century Crusader chapel abandoned in 1345 and a 4th-century Byzantine basilica, destroyed by an earthquake in 746. The original Basilica was built by Emperor Theodosius I over the rock on which Christ was believed to have prayed. The current Basilica of the Agony was built from 1919 to 1924 using funds from 12 different countries, which gave it its common name, Church of All Nations.
The symbols of each country that contributed to the church are incorporated into the inlaid gold ceilings of each of 12 cupolas.
The front of the church features a colorful façade supported by a row of pillars. The mosaic above the entrance depicts Christ as the link between God and humanity.
