The Church of the Holy Savior, or Surp Amenap’rkitch, located in eastern Turkey within the Ani Archaeological Site, was built in 1035 on the orders of Prince Abulgharib Pahlavuni to house a piece of the True Cross. The church’s design is unique, with 19 external sides, an octagonal interior, and a huge central dome supported by a tall drum. The church remained largely intact until 1930, when it was struck by lightning and the entire eastern half collapsed.
