Lassea was one of the ports of the Roman city Gortyn, the capital of crete in Roman Era, and is located at the site of the current settlement Chrysostomos. Lassea was rich in copper deposits, which were used for trading copper. Saint Paul mentions the town in his Acts for his stay on Crete.
“… we sailed to the lee of Crete opposite Salmone … and came to a place called Fair Havens, near the town of Lasea … after the fast [Day of Atonement in late September] … the majority decided that we should sail on, hoping to reach Phoenix and winter there … so they weighed anchor and sailed along the [southern] shore of Crete … the ship was caught by the storm … we passed to the lee [south] of a small island called Cauda, we were hardly able to make the lifeboat secure.” (Acts 27:7-16; NIV translation)
On the west end of the beach of Chrisostomos there is a "line" of rocks, that heads towards the small isletTrafos. This is the old dock of the ancient town Lassea. The rocks were in that place since 1960s, when they were used for the construction of the Oil Tanks in Kali Limenes. On the island and on the beach, opposite Trafos, you can still see remains of the ancient town of Lasea. A bit further to the west, tombs have been identified.
