8 Fascinating Facts You Didn’t Know About Santorini

Santorini is known for its breathtaking sunsets, whitewashed buildings, and fascinating history. But beyond its iconic views and architecture, this island is filled with stories, secrets, and wonders that many visitors never hear about. Here are eight surprising facts about Santorini that may inspire you to see this gem island in a whole new light.

1. It Was Once a Single Island Called “Stroggili”
Before its volcanic eruption around 1600 BCE, Santorini was a round, single island called Stroggili, meaning “the round one” in Greek. This catastrophic eruption led to the island’s current crescent shape and created the caldera that now sits submerged in the Aegean Sea.

2. One of the Most Active Volcanic Areas in the World
Santorini’s famous caldera is part of one of the most active volcanic areas on the planet. The volcano that shaped Santorini is still active, though it’s carefully monitored. The most recent eruption occurred in 1950, and Nea Kameni, the small island within the caldera, is home to geothermal activity, hot springs, and unique volcanic rock formations.

3. The Atlantis Connection
Santorini is often linked to the legendary lost city of Atlantis. The great eruption that reshaped the island may have inspired Plato’s story about the sudden disappearance of an advanced civilization. This theory draws many history lovers and mystery-seekers to Santorini each year.

4. A Unique Climate Ideal for Wine Making
Santorini’s unique climate, with high winds, volcanic soil, and low rainfall, makes it an exceptional location for producing wine, particularly the Assyrtiko grape. These vines are trained in a unique “basket” shape (kouloura for the locals) to protect them from the island’s harsh winds. The mineral-rich soil gives Santorini’s wines a unique, crisp taste that can’t be found elsewhere.

5. Santorini Has No Natural Sources of Fresh Water
Due to its volcanic geology, Santorini has no natural sources of fresh water. The water supply was once scarce and limited to cisterns, but today, desalination plants convert seawater into drinkable water for residents and visitors alike. This scarcity of water is also why certain agricultural practices, like growing grapes for wine, have been so meticulously adapted to thrive in this environment.

6. The Famous Sunset Town of Oia Was Rebuilt After an Earthquake
Oia, known for its incredible sunset views, was heavily damaged by a powerful earthquake in 1956. Afterward, the town was rebuilt with preservation in mind, carefully maintaining its traditional architecture and style. Today, it stands as one of the most picturesque spots in the world, attracting thousands of sunset watchers every evening.

7. Pumice Stone Exported Around the World
Santorini’s volcanic history left behind a vast amount of pumice stone, which became a valuable export. In the past, Santorini exported this natural resource to countries worldwide, where it was used in construction and manufacturing, even helping to build the Suez Canal.

8. A Hidden Gem for Hiking Enthusiasts
While Santorini is famous for its beaches and sea views, it also offers incredible hiking trails. The Fira to Oia trail, winding along the caldera, is particularly popular, offering panoramic views of the Aegean Sea, the island’s rugged landscape, and hidden chapels along the way. Hiking provides a unique way to experience Santorini’s quieter, more natural side.
