A typical Serbo-Byzantine church has a rectangular foundation, with a major dome in the center with smaller domes around the center one. The inside of the church is covered with frescos that illustrate various biblical stories and portrays Serbian saints. The Monastery of the Holy Archangels in Prizren was founded by the Serbian Emperor Stefan Dušan between 1343 and 1352 on the site of an earlier church, part of the Višegrad fortress complex. It was the burial church for Emperor Dušan, and represented the culmination of the Serbian ecclesiastical architectural style, that led to the birth of the Morava school style.
