# List of largest Eastern Orthodox church buildings

This is a list of the largest Eastern Orthodox church buildings in the world, based on area and capacity. Any Eastern Orthodox church building that has a capacity of 3,000 people or more, can be added to this page. Entries are included even if a premises otherwise meeting the criterion currently does not function as a church. For example, the Hagia Sophia in Turkey is included – it was originally built as a church but was later converted into a mosque. Sorting is done by volume (priority) and area. The church buildings are listed in alphabetical order according to country. The churches are from various jurisdictions of the Eastern Orthodox Church.
