Raà ¡ka architectural school (), also known as the Raà ¡ka style (àðÃÂúø ÃÂÃÂøû, Raà ¡ki stil), or simply as the Raà ¡ka school, is an ecclesiastical architectural style that flourished in the Serbian Middle Ages (ca. 1170âÂÂ1300), during the reign of the Nemanjiàdynasty. The style is present in several notable churches and monasteries: Studenica, PeÃÂ, SopoÃÂani, MoraÃÂa, Arilje and many others. This style descends from the traditional Byzantine architecture with early Christian church-design, and often utilizes a combination of stone and wood material. The Byzantine style was contrasted with that of the Latin-Romanesque style in Zeta. With the reunification of Serbia proper (Raà ¡ka) and Zeta (Duklja) under Stefan Nemanja, a cultural bridge connected Serbia with the best-known centers of world art, Thessaloniki and Constantinople on the one side and the Republic of Venice and the Adriatic coast on the other.
