A 4th-century A.D. chapel that may be the oldest Christian place of worship in Thessaloniki was discovered by archaeologists beneath an early Christian basilica, itself unearthed during construction of the Sintrivani metro station in the northern port city.

On either side are a number of birds, of which seven still survive, two of the right and five on the left.
