 Only stone walls, which were replacing the earlier mudbrick and wood walls, were strong enough to support the weight of a tiled roof.The earliest finds of roof tiles of the Archaic period in Greece are documented from a very restricted area around Corinth, where fired tiles began to replace thatched roofs at the temples of Apollo and Poseidon between 700 and 650 BC.Spreading rapidly, roof tiles were within fifty years in evidence for a large number of sites around the Eastern Mediterranean, including Mainland Greece, Western Asia Minor, Southern and Central Italy.
