Santorini's Caldera

From astounding sights to impressive geomorphological locations, it’s not hard to see why, even though many are familiar with the beauty of the Greek islands, Santorini stands out and remains a pleasant surprise to anyone who sets eyes on it, due to its wild beauty and unparalleled views. Such a location of unique beauty is the caldera of Santorini, which looks like a large lagoon, but its history dates back millions of years and has a long story to tell.

So, let’s dig into one of the oldest surviving natural wonders of the world and shed some light on the factors that formed it into the beauty that it is today.

What is Santorini’s Caldera?

The unique caldera of Santorini is a captivating combination of natural beauty and historical significance. This incomparable geological formation is surrounded by the lovely villages of Oia, Fira, Firostefani, Imerovigli, and Akrotiri, which are perched on its dramatic cliffs offering unparalleled views of the Volcano of Santorini and the vast Aegean Sea. The whitewashed houses, hotels with pools and Jacuzzis, cliff-hanging restaurants, and views from beyond this world, create a stunning setting totally worth seeing!

The magic of the caldera changes throughout the day. In daylight, it gives a wide view of its stunning architecture and crystal-clear waters, while at night, its lighted villages create a really romantic and atmospheric scene. However, the beauty of the caldera is particularly enhanced during sunset, when the golden colors cast a magic glow on the white buildings, creating a beautiful spectacle!

The name of this unique formation is derived from the Spanish word ‘’caldera’’ meaning ‘’cauldron’’ or "deep pot" describing the bowl-like shape that it has. It was created from an eruption that lasted for two weeks and is 4 km wide and 2 km deep. It is also the largest in Europe and ranks among the five largest globally, covering approximately 25 square kilometers (about 10 square miles), while its diameter reaches 16 kilometers.

The Caldera's Eruptive History

The history of Santorini’s Caldera is written millions of years ago. Then, one of the most important events in history, a catastrophic eruption, known as the Minoan eruption, which occurred around 1613 BC, transformed the island's landscape as it is today. This event not only gave a new shape to Santorini but also created three islands surrounding the caldera: Santorini (the main island), Aspronisi, and Therasia. What is more, at the caldera's center, two smaller islands were created, Palea Kameni and Nea Kameni, formed from solidified lava. Palea Kameni was formed by a volcanic eruption in 47 AD, while Nea Kameni was created approximately 1,200 years later.

Before the eruption, Santorini, then called Thera, was home to a thriving Minoan civilization. However, the eruption of 1613 BC was so devastating that the Minoan civilization was partly destroyed, as the volcanic ash covered entire cities all over the island. In the years following the eruption, gradually the island was transformed into the crescent-shaped island we see today and was repopulated.

Over the years, the volcanic activity continued to shape the island, leading to the form of the Caldera today, offering great views from its villages that are clung to its towering cliffs. These villages are admired for their unique beauty, while the two volcanic islands of Palea Kameni and Nea Kameni, remain popular destinations and are visited yearly by people all around the world, who come to witness the powerful forces that formed this extraordinary landscape.
