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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
