The first step towards creating a church based on an imperial mausoleum was made around 320, when Constantine connected what was supposed to become his own mausoleum, with a church structure.
Prvi korak prema stvaranju crkve temeljene na formi carskog mauzoleja učinjen je oko 320. godine kada je Konstantin, ono što je trebalo postati njegov osobni mauzolej, povezao s crkvenom strukturom.
