Olous is a sunken ancient Dorian city on the isthmus that links the Spinalonga peninsula to the mainland, at present-day Elounda in the Lasithi region of eastern Crete. Today only scattered wall bases survive, submerged in the shallow water of Elounda Bay, and you can see them by snorkelling or swimming on a calm day. The site is free and open, with no gate and no entrance fee.
Olous flourished across the Minoan, Hellenistic, Roman and Byzantine periods. The city minted its own coins, ran its own harbour, and traded across the Mediterranean, linking Crete with the Aegean islands and civilisations beyond. Its ruins reveal the daily life, culture and architecture of the people who lived on this coast for centuries.
What is the Archaeological Site of Olous?
Olous was a submerged city of ancient Crete at the modern town of Elounda, in the Lasithi regional unit. It sat on the isthmus connecting the Spinalonga peninsula to the mainland, overlooking Mirabello Bay. According to the Stadiasmus Maris Magni, an ancient coastal navigation guide, Olous had a harbour and lay 260 stadia from Chersonasus and 15 stadia from Camara. Its coastal position made it a hub of trade and cultural exchange.
The site’s geographical coordinates are roughly 35.2562° latitude North and 25.7335° longitude East. On Google Maps the entry point is marked “Archaeologikos Choros Olous”.
Underwater and coastal remains include the lines of old streets and roads, building foundations, sections of the harbour wall, and traces of fortifications and gates. Finds recovered from the area, pottery, tools, inscriptions, marble statue fragments and Roman tombs, have been documented by the Ephorate of Underwater Antiquities. Together they mark Olous as a working commercial port rather than a monumental city.
The History of Olous: Deities, Coins and Trade
Olous was an independent city-state that minted its own coins and worshipped its own gods before it slipped beneath Mirabello Bay. It was one of the more powerful settlements on this coast, with its own port and currency, and it held long-running boundary disputes, later settled by treaty, with the neighbouring hillfort of Lato.
The city developed on a maritime crossroads that connected northern Crete with the Aegean islands and the wider Mediterranean. Because ancient writers say little about Olous, most of what we know comes from coins, inscriptions and archaeological finds. Ancient texts recovered from the ruins link Olous with Knossos and with the island of Rhodes.
The Temple of Britomartis and the coins of Olous
Olous worshipped the goddess Britomartis, whose wooden statue in the city was attributed to the mythical craftsman Daedalus. Britomartis appears, alongside Zeus Tallaios, the city’s chief deity, on coins minted at Olous around 330–280 BC. Inscriptions also point to a cult of Asklepios. These coins and inscriptions are the clearest surviving evidence of the city’s religious life.
Why and when Olous sank?
Researchers propose two theories for the submersion. One holds that a coastal shift from an earthquake in the Roman era gradually put the city underwater; another attributes the collapse to an earthquake or landslide around 780 AD. Either way, the ancient city sank into the sea, and its remnants are visible when the water is calm.
Later history is easier to trace. Olous prospered under Roman and Byzantine rule until Arab raids in the 7th century damaged its trade-based economy. During the Venetian period the wider Elounda area revived: the harbour was rebuilt and a large salt-pan complex was developed in the shallows. Stone from the ancient city was reused to build the fortress on the Spinalonga islet, which guarded the entrance to the harbour.
Where is Olous and What Can You See Today?
The Olous Archaeological Site is on the shore of Elounda in northeastern Crete, on the Gulf of Mirabello. Elounda is a beach village known for its clear waters, beaches and resorts, and Olous sits right at its edge.
Today, the only visible remnants of the city are scattered wall bases in the shallow water, best seen by snorkelling or swimming on a calm day. There is no fenced enclosure and no admission gate; you walk the seafront and look for the lines of stone through the water.
The surrounding area adds to the visit: Mirabello Bay, the Spinalonga peninsula, and Spinalonga Island itself with its Venetian fortress. Together these make Olous one of the more atmospheric coastal Crete landmarks in Lasithi.
The Kolokytha peninsula: basilica, mosaic, windmills and bridge
About 1.5 kilometers (0.93 miles) from the site, on the Kolokytha (Kolokitha) peninsula, are the sights most visitors actually walk to: the stone windmills that are the area’s trademark, an early Byzantine basilica with a mosaic floor, the Ascension Church, and a small stone bridge lined with fishing boats. You can reach them on foot or by car, and the walk along the water is part of the appeal.
What is the Historical Origin of Olous?
Olous began as a coastal settlement on the northeastern shore of Crete and grew because of the sea. Its strategic position on Mirabello Bay suited marine activity, trade and contact with other Mediterranean civilisations, and it thrived through the Minoan, Hellenistic, Roman and Byzantine eras.
The city was identified as an archaeological site through systematic excavation over many years. Work on land and underwater has uncovered streets, house foundations, artefacts and other evidence that let archaeologists reconstruct how the people of Olous lived, traded and worshipped.
