Also known as the Church of Agony because it is built over the rock where Jesus agonized about his death, this 4th-century church has been rebuilt many times, the most recent structure being the result of financial contributions from 12 nations. To commemorate the benefactors, the church was designed with 12 domes adorned with each country's coat of arms. The rock in the center of the nave is the remnant of the ruined Byzantine church. The plan of the Byzantine church is outlined on the floor in black marble. Next to the church is the surviving part of the Garden of Gethsemane with its centuries-old olive trees.
