Lissos and Syia were the harbours of the city of Elyros, the most important ancient city of the area, located near the village Rodovani. It was established in the Classical period and flourished until the Late Antiquity. The early history of the city is unknown. Based on inscriptions and coins of the 3rd century BC, we know the city allied with King Magas of Cyrene, and joined the League of Oreians. Lissos had powerful trading and fishing navy.
There were discovered ruins of theatre, aqueduct, cemetery, and baths of the ancient times, and Palaiochristian basilicas. In the area, there were also found many votive objects, which are now exhibited at the Archaeological Museums of Heraklion and Chania. In no other city of Crete, apart from Gortys, there were found so many pieces of sculpture. This fact testifies the prosperity and the power of the Asclepieion of Lissos. Lissos has its own coins with the images of Artemis and dolphin and the word LISION (of the Lisians).
Beside the Asklepieion and the Roman necropolis there are also two Greek Orthodox churches: Agios Kyrikos has some nice frescoes, and the chapel of Panagia is built with ancient marble blocks.
The small beach is a coarse pebble beach. Nobody lives in Lissos nowadays. You can reach it from Sougia by boat or by foot (90 minutes walk).
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
