Archaeologists have discovered a fifth-century mosaic bearing a message to early Christians.
The artwork was uncovered in Turkey's ancient city of Olympus at a church entrance.
The inscription translates to "only those on the right path may enter here," according to Turkey's Ministry of Culture and Tourism.
The mosaic adorns the entrance to Church No1 in Olympus' ancient Kumluca district.
Gokcen Kutulus Oztaskin, associate professor at Pamukkale University and excavation director, said: "This mosaic inscription is strategically placed at the very entrance of the church."
The decorative flooring extends from the entrance into the church interior, forming part of recent archaeological finds at the site where crews have been working since 2006.
The mosaics feature geometric patterns and botanical designs throughout various areas of the building, with additional inscriptions identifying churchgoers who funded the construction.
Oztaskin said: "These finds confirm Olympus as one of the richest ancient cities in the Lycia region in terms of mosaic flooring."
