The period of architecture termed Early or Paleo-Christian lasted from the first Christian Church buildings of the early 4th century until the development of a distinctly Byzantine style which emerged in the reign of Justinian I in the 6th century, foundation of Constantinople by Constantine in 330 CE. Some of the earliest Christian churches were constructed by the Arsacid dynasty of Armenia, where king Tiridates III converted to Christianity in 301. The small aisleless Kasagh Basilica at Aparan in the Kingdom of Armenia is traditionally dated to the 4th century.
