The Church of Christ Pantocrator is located on the peninsula of Nesebar, Bulgaria. The church, along with the entire island and all of the historical structures are protected by UNESCO. The structure was erected in the 13th century and is a rare example of a religious structure which has not experienced significant changes through the centuries. Although small in dimensions (16 meters by 6.7 meters) this cross-domed church still remains one of the best examples of period architecture in European history. Other architectural features of the structure include three altar niches and a narthex. Also, there are semicircular apses inside and pentahedal located on the exterior. The facades of the building are segmented by richly decorated blind niches.
