The island that three empires used and one novelist made famous
Spinalonga is a small island — about 0.4 square kilometres — sitting at the mouth of the Elounda gulf in eastern Crete. Three things made it important. The Venetians recognised that whoever controlled the narrows between Spinalonga and the Kolokytha peninsula controlled the finest natural harbour in eastern Crete. The Ottomans could not dislodge the Venetian garrison for over a century. And in 1903, after the Ottomans left, the Greek government established a leper colony there that operated continuously until 1957 — the last functioning one in Europe.
Victoria Hislop’s novel The Island (2005), set partly on Spinalonga, brought a new wave of visitors who arrived having read the book and found the reality matched the atmosphere. The ruins are atmospheric in an uncomfortable way — the scale of normal life that existed here, the houses and church and kafeneion and streets, alongside the knowledge of what life meant for the people who lived there.
The island is reached by short boat crossing from Elounda (10 minutes, €8–12 return) or on a longer bay cruise from Agios Nikolaos (about 30 minutes each way, typically €15 with a short stop at Kolokytha). Entry to the island is included in the boat ticket from most operators; if not, it is €8 separately.
Three centuries of Venetian fortification
The Venetians began fortifying Spinalonga in 1579, responding to Ottoman expansion across the eastern Mediterranean. The fortress was built to the highest contemporary standards of military architecture — the curving bastions, the landward walls designed to deflect cannon fire, the underground magazines — and it worked. The Ottomans took all of Crete in 1669, but Spinalonga, along with the islands of Gramvousa and Souda, held out.
Spinalonga finally passed to the Ottomans in 1715 under a treaty — not by force. It was the last Venetian holding in Crete. The Ottomans settled it with a civilian population and it became a prosperous small town of about 300 people. The Dante’s Gate — the main tunnel entrance cut through the Venetian walls — was so named because passing through it, into the world of the colony, felt to contemporaries like passing into another realm. The tunnel is intact and you walk through it to enter the interior.
The leper colony years: 1903–1957
When the Ottoman population left in 1903, the Greek state saw a practical use for Spinalonga’s isolation. Leprosy (Hansen’s disease) had no cure and no effective treatment; the policy across Europe was segregation. Spinalonga’s water, existing buildings, and natural isolation made it the designated location for Cretan and, later, Greek lepers from across the country.
At its peak the colony held around 1,000 people. The conditions were harsh initially — inadequate food, no medical care, a death sentence by another name. Over the decades this improved: a doctor was eventually stationed there, a pharmacist, a church with a priest, a kafeneion, a barber’s shop. People married on the island, had children (children born without the disease were removed and raised on the mainland). The colony had its own elected administration.
The last resident left in 1957 when effective antibiotic treatment finally allowed survivors to leave. The buildings were abandoned in place.
What you see on the island today
The walking circuit of Spinalonga takes 1–1.5 hours at an easy pace. The path enters through Dante’s Gate and runs clockwise around the interior.
The main street of the former settlement is the most immediately striking section: a row of two-storey houses in reasonable condition, doorways open, rooms visible. The buildings are not restored or curated — they are in the state they were left in, which gives the site an unusual atmosphere of genuinely abandoned life rather than presented archaeology.
The church of St George at the settlement’s centre still has its painted interior partially intact. The Venetian fortifications on the west and north side are the best-preserved military architecture; the views from the walls across the gulf to Elounda and the mountains behind are exceptional.
The hospital building near the southern end shows the institutional layer of the colony’s later years. The Venetian cisterns that supplied fresh water to the island are visible near the main gate.
Getting there: boats and logistics
The most common route is from Elounda, 10 km north of Agios Nikolaos — small boats leave approximately every 30 minutes between 9 am and 5 pm in season, and the crossing takes 10 minutes. Elounda has a small quay with multiple competing operators; the ticket includes the island entry in most cases.
The Spinalonga boat trip from Agios Nikolaos combines a bay cruise with the island visit and is the most scenic approach. The Spinalonga, Elounda, and Agios Nikolaos trip with BBQ lunch extends this into a full-day format with a meal — useful if you want to combine the island with a swim stop in the Elounda bay.
For visitors based in Heraklion wanting to cover Spinalonga and Agios Nikolaos in a single day, the Heraklion to Spinalonga and Agios Nikolaos cruise handles both directions with transport from the city.
The practical tip that makes a real difference: take the first boat of the day (9–9:30 am departure from Elounda). The island receives several thousand visitors on a summer day; by 11 am the interior is crowded and the ruins feel less like a place and more like a sight. An hour at the beginning of the day, before the coach tours arrive, is the Spinalonga worth coming for.
Spinalonga in context with eastern Crete
Spinalonga sits within a half-day of Agios Nikolaos and can be combined with a swim at Elounda or a drive to the Lassithi plateau. If you are staying in Heraklion, a full-day circuit — drive east to Agios Nikolaos, boat to Spinalonga, lunch in Elounda, drive back — covers eastern Crete’s highlights without feeling rushed.
