A fragment of a clay roof tile bearing the name Cilo was discovered in the Western Wall Tunnels, west of the Herodian Temple Mount. This impression joins other private stamps of the Late Roman period (second and third/early fourth century CE) previously found in Jerusalem and its environs. The private stamps of the Roman period may be attributed to private workshops that operated in Aelia Capitolina after production ceased in the military workshop at Binyene Ha-Umma.
