In Makry Gialos, at the place Katovigli, near the church of the Dormition of the Virgin, have been unearthed remains of a Roman Villa. Pendlebury (BSA XXXIII p. 100) had already noted the existence of a Roman settlement here. Excavations begun in 1977 (not yet completed), have shown that there were indeed large domestic establishments, dated from the 1st century BC to the 3rd century AD, but it is not possible at this stage of the excavations to draw definite conclusions. One room after another has been discovered and the whole excavation so far, covers an area of roughly 1500 sq.m.

The houses of Tylissos were built during the LM I period (16th-15th century B.C.). Additions were made on House A in the LM II (15th-14th century B.C.) and on House C during the LM III period (14th century B.C.). The site was destroyed by fire in the 14th century B.C. and re - inhabited in historic times as is attested by ruins of later houses over the Minoan ones. Tylissos was excavated by Joseph Chatzidakis in 1902-1913. In 1954, in the course of restorations, parts of a paved court were revealed to the west, and a small stoa with five columns to the north of the Square of the Altar.
The monuments were restored by the Archaeological Service (under the direction of Nicolaos Platon) in the period between 1954 and 1962. All three houses were again restored in 1990-1994.
