This is a list of tallest Orthodox church buildings in the world, all those higher than 70 metres.
Traditionally, an Orthodox church building is crowned by one or several domes with Orthodox crosses on the top of each.
The number of domes on individual churches often serve a symbolic purpose.
An Orthodox church building may also have a bell tower or zvonnitsa, either a part of the main church building, or standalone structure.
Typically, a bell tower is higher than the main temple.
