Church of Agioi Treis
In the Mitropoleos district, near Omonoia Square, you will spot the Church of Agioi Treis, dedicated to Saints Gourias, Samonas, and Abibus. It is a single-aisled, timber-roofed basilica featuring a three-sided apse on the eastern side and a later open arched portico along both the southern and northern sides. Traces of fire can still be seen on the exterior masonry, evidence that the church once burned—an event that may also explain the plastering of its surfaces, which in turn covered the original fresco decoration. Later restoration efforts revealed parts of the fresco, including figures of saints and the church’s dedicatory inscription – according to which, the interior frescoes date to 1401. The frescoes on the exterior surfaces are also attributed to the same period. This painted ensemble follows the anti-classical trend of the late Palaiologan period, reflecting the evolution of Kastoria’s artistic tradition in the early 15th century. During your visit, the surviving sections will allow you to discern the dynamism and distinctive features of this artistic phase, which connects local artistic production with the broader trends of the Byzantine world.
