Byzantine styles, while Morava style was influenced by Vardar style, with distinctive Serbian design elements. Western European gothic and romanesque church architecture can be seen mostly in the southern parts of Serbia. Early signs of renaissance can be seen during Stefan Lazarević reign through his Resava School and the Morava architectural style, but would quickly be snuffed out when the Ottomans took full control of Serbian lands, with no clear examples of renaissance architecture present in Serbia until historic revival movements in the modernity period. Raška Style Raška architectural school in Serbian architecture during the Middle Ages, covers the period from the seventh decade of the 12th to the end of the 13th century, with Stefan Nemanja's Đurđevi stupovi (around 1170) being taken as the starting points of the style, and Stefan Dragutin's Church of St. Achillius (around 1296) as the end point. However, this border is only indicative because there are later ecclesiastical objects that belong to another style, but are architecturally constructed in Raška style, such as the monastery churches of Visoki Dečani and Banjska, which were erected in the first half of the 14th century and at a time when the Vardar style dominated. The style itself was named after the Raška river, where the then Kingdom of Serbia gravitated around. A large example of these Raška style churches and monasteries are also located in Montenegro and Bosnia and Herzegovina. The basic characteristic of this style is a single-nave basilica, single-drum dome structure. On the west side, there is usually a narthex, while on the south and north, there are lower wards, usually transepts and parecclesions (or apse). The external designs of the church buildings were done in romanesque style, indicating direct links with the seaside, Adriatic coastal towns (Kotor, Dubrovnik and others), which were under Nemanjić's control at the time. The so-called golden age of Serbian painting, which began with the fresco painting of Đurđevi stupovi around 1175 and ended with Gradac around 1275, culminates with Sopoćani. After this period, the so-called Vardar style with its frescoes, developed under the influence of the Palaiologos Renaissance. Many Raška styled churches and monasteries would have elements of their design altered over time. Studenica, Žiča, Gradac for example had their designs noticeably altered, ether due to natural disasters or pillages, requiring extensive repairs and restorations to the structures, or general alterations to the original designs through the building's expansion.
