Macedonia became an extremely fertile area of architectural production from c. 1280 to c. 1370. The beginnings of the architectural activity in the region witnessed an influx of builders from the Despotate of Epiros and the Empire of Nicaea. Once its prestige was reestablished, by around 1300, Thessalonike began to exert influence of its own. The role of Thessalonike in the development of 14th-century ecclesiastical architecture in the Balkans was restricted both geographically and chronologically. Thessalonike, even at the height of its architectural productivity, was only one of the sources of architectural influence in Macedonia. During the first decades of the 14th century its impact was paralleled by that of Epiros, emanating at the time from another newly risen prosperous center, Ohrid. By the 1340s both Thessalonike and Ohrid were eclipsed by the third major center of regional architectural production — Skopje, the capital of Stefan Dushan’s short-lived Empire.
