Byzantine Sites in Ukraine: Explore Crimean Churches, Coastal Forts and Ancient Cherson
Byzantine sites in Ukraine include the Christian buildings of ancient Cherson, a domed church in Kerch and fortifications along Crimea’s southern coast. The remains range from excavated basilica plans within a large ancient city to standing medieval masonry reused and altered by later builders.
These examples are concentrated in Crimea. They cover urban worship, coastal defence and churches whose architectural details connect them with the wider Byzantine world. Roman, Byzantine, Genoese and much later construction may occur within the same site, so the older structures need to be distinguished from subsequent additions.

Chersonesos: basilicas within the ancient city
Chersonesos, known as Cherson in Byzantine times, preserves the remains of Christian churches among the streets and buildings of an older Greek and Roman settlement. The church conventionally called the 1935 Basilica takes its name from the year of its excavation; its original dedication is unknown. Generally dated to the sixth century, it occupied a site with earlier building phases.
The excavated church belongs to a wider urban area containing residential blocks, water installations and successive fortifications. Christian basilicas changed the religious buildings within that inherited town plan. The large Cathedral of Saint Vladimir above the archaeological remains is a nineteenth-century building in a Byzantine-inspired style, separate from the medieval churches below.
The archaeological setting has also undergone recent alteration. In 2026, UNESCO placed Chersonesos on the List of World Heritage in Danger, citing new construction and extensive associated excavation affecting the site’s authenticity and integrity. Descriptions and photographs of the ruins should therefore be understood alongside that documented change.
Saint John the Baptist in Kerch: a domed stone-and-brick church
The older part of the Church of Saint John the Baptist in Kerch has a cross-domed plan with four supports beneath the central dome. Three apses project from its eastern end, while the central crossing rises above the lower surrounding spaces. Bands of thin brick alternate with pale stone in the walls.
Columns, capitals and other carved pieces were reused from earlier buildings. An inscription on one column has often been read as a date in the eighth century, but it commemorates a death and does not securely date the construction of the church. The chronology of the older building remains debated.
Later western extensions use different masonry and stand at a higher floor level. Restoration exposed parts of the ancient foundations and removed later wall coverings. The older domed core and its patterned masonry provide the main architectural interest, with small surviving areas of medieval fresco adding evidence of its former painted interior.
Aluston: a Byzantine foundation with later defensive towers
Aluston Fortress stands on a hill above the southern Crimean coast. Founded under Justinian in the sixth century, its early enclosure used thick walls of local stone set in lime mortar. The settlement expanded beyond this first compact fort over subsequent centuries.
Genoese builders later enlarged and rebuilt the defences. The surviving round tower known as Ashaga-Kule belongs to that later defensive system, with a broad cylindrical body and a former fighting platform at the top. Other stretches of wall preserve different phases of the fort’s development.
Excavation also identified a medieval church within the settlement, with an inscription recording a restoration in 1404. The fortress combines an early Byzantine foundation with later urban growth and rebuilding; its most prominent tower should not be assigned to Justinian simply because the fort began during his reign.
