Daphni Monastery is the Byzantine monastery in Greece famous for its 11th-century gold-ground mosaics and cross-in-square church.
The monastery stands near Athens, on the ancient Sacred Way toward Eleusis. Its katholikon, or main monastery church, was built in the late 11th century and belongs to the mature Middle Byzantine architectural tradition.
The mosaics cover the dome, apse, vaults, and other surfaces. Their imagery includes Christ Pantocrator, scenes from the life of Christ, and figures of saints. The backgrounds use gold tesserae, producing the luminous effect associated with Byzantine interiors.
Daphni is sometimes confused with Hosios Loukas and Nea Moni, two other major Greek Byzantine monasteries with celebrated mosaic programs. Daphni, Hosios Loukas, and Nea Moni are often studied together as outstanding examples of Byzantine mosaic art.
