Extra moenia (also: extra muros) is a Latin phrase that means outside the wallsoroutside the walls of the city.[1]
The phrase is commonly used in reference to the original attributes of a building, usually a church, which was built outside the original city walls. Hence, when a city expands over time, a church which was originally outside the walls might end up in the center of the larger city; subsequently, to retain the original architectural context, it would be referred to as extra moenia.[2][3] The term is also used to indicate an occurrence or activity taking place outside the venue where it would normally be found or reside.[citation needed]
