Saint Nicholas of Kasnitzis Church

A refined early Byzantine basilica, broadly contemporary with Agios Stefanos. It is especially notable for its exterior and interior frescoes, including monumental depictions of the Archangels and an unusual cycle of Passion scenes.

One of Kastoria’s most distinctive early Byzantine churches, likely to date from the early 10th century. Its rare domed triconch plan makes it architecturally unique in the town, with later additions to the western end. Inside are layered frescoes from different periods, including a 12th-century Nativity scene above the west door.

One of Kastoria’s most important early Byzantine churches, Saint Stephen dates possibly to around 900 AD. Its exterior is notable for alternating stone and brick bands and distinctive cartwheel brick motifs in the apse. Inside, surviving frescoes — though damaged — include an early Last Judgement in the narthex, and later 12th-century Christological imagery in the nave.

One of Kastoria’s more mature Byzantine churches, Agioi Anargyroi (11th century) reflects a shift toward broader and more balanced basilica proportions. It is especially notable for its richly carved doorway and decorative brickwork on the exterior. Inside, layered frescoes from the 11th–13th centuries include figures of saints and remnants of a founders’ portrait.

Set on the lakeshore a short drive or walk from Kastoria, the Monastery of Panagia Mavriotissa is one of the most atmospheric Byzantine sites in the region. The core church likely dates to the 11th century, with later additions including a narthex and a 14th-century side chapel. It is especially renowned for its extensive frescoes from multiple periods, including a notable Koimisis on the west wall.
