and building constructions. The emergence of the Kingdom of Serbia (and other Serb medieval states), subsequent Empire, and fall under Byzanties, Ottomans and Habsburgs would leave an everlasting impact in Serbian and Serb culture and the architecture build then and afterwards. From romanesque, to gothic, Ottoman, Byzantine, moorish and local styles (Raška, Vardar, Morava), this period laid the foundations for future historic revival styles, as well as Serbia's own national architectural style. The territories of medieval Serbia would often shift during this period, which would leave many Serb architectural works in Bosnia and Herzegovina, Montenegro, North Macedonia, and parts of Albania, Bulgaria, Croatia, Greece, Hungary, and Romania. The legacy of medieval Serbian architecture is evident through churches, monasteries, fortresses, and castles preserved despite the turbulent history. While very few folk and vernacular buildings survived from the medieval period, their trace influences can be seen through the many vernacular buildings constructed in the modernity period. Medieval Christian architecture Church of the Holy Apostles Peter and Paul is one of the few remaining building from early Middle Ages and UNESCO World Cultural Heritage site. Prohor Pčinjski Monastery was founded 1067–1071 by the Byzantine emperor Romanus IV in honor of Saint Prohor of Pčinja. Church architecture mostly developed under the patronage of the Serbian state, with rarely any mentions of what specific architect and engineer designed the church building (records of specific fresco artists remain). The most distinctive piece of medieval Serbian architecture was the Studenica monastery founded by Stefan Nemanja, the founder of Nemanjić dynasty in c. 1190. This monastery also featured significant works of art including its Byzantine style fresco paintings. Its church also features extensive sculptures based on Psalms and the Dormition of the Theotokos. UNESCO added this monastery to its list of World Cultural Heritage sites in 1986. It was the model for other monasteries at Mileševa, Sopoćani and the Visoki Dečani. The influence of Byzantine art became more influential after the capture of Constantinople in 1204 in the Fourth Crusade when many Greek artists fled to Serbia. Their influence can be seen at the Church of the Ascension at Mileševa as well as in the wall paintings at the Church of the Holy Apostles at Peć and at the Sopoćani Monastery. Icons also formed a significant part of church art. Several ecclesiastical schools emerged during the middle ages. Raška and Vardar styles were heavily influenced by romanesque and
