Some pre-Romanesque churches from the 9th century in the middle Danube region probably have their origins in the architecture of the Adriatic region. The aim of the first part of the article is to contribute to find the origin of the basilica on Receskut Island (Hungary) and identify the origin and form of the basilica on Bratislava Castle (Slovakia), and thereby help to specify their dating. The aim of the second part is an attempt to reconstruct the building development and design of the church No. 10 in Mikulčice (Moravia) and answer the question of the origin of this church.
