The design is particularly evident in the cave houses carved into the volcanic rock, which are naturally more resistant to shaking. This architectural adaptation is a testament to the resilience of Santorini’s inhabitants and their ability to live in harmony with the island’s dynamic environment.

3. The "Invisible" Island Economy

While tourism is the most visible aspect of Santorini’s economy, the island also has a less obvious, but significant, agricultural sector. The island’s volcanic soil and microclimates are ideal for growing unique crops like the Assyrtiko grape, fava beans, and capers. These products are not only staples of local cuisine but are also exported to other parts of Greece and beyond. Despite the dominance of tourism, these traditional agricultural practices play a vital role in preserving Santorini’s cultural heritage and providing a sustainable livelihood for many of its residents.

4. The Kallisti Gaudos Naval Base Controversy

In the late 1960s, during the military dictatorship in Greece, there was a controversial plan to establish a naval base on Santorini. The base, known as "Kallisti Gaudos," was intended to bolster Greece’s strategic position in the Aegean Sea. However, the plan faced significant opposition from locals who feared it would disrupt the island’s traditional way of life and damage its natural beauty. After much debate and protest, the project was eventually shelved, and Santorini’s pristine environment was preserved.

5. The Forgotten Village of Mesa Gonia

Mesa Gonia, once one of the most prosperous villages on Santorini, was largely abandoned after the devastating earthquake of 1956. While many residents moved to safer areas, a few families stayed behind, and the village remained frozen in time for decades. Today, Mesa Gonia is slowly being rediscovered, with some of its historic buildings being restored. It offers a hauntingly beautiful glimpse into Santorini’s past, away from the bustling tourist centers.

6. The Santorini Locust Swarm of 1895

In 1895, Santorini faced an unusual and devastating natural disaster: a swarm of locusts that descended on the island and destroyed much of its agricultural crops. The locust invasion was so severe that it threatened the island’s food supply and economy. In response, the local government organized a massive effort to exterminate the pests, including offering bounties for locusts collected by residents. The event is remembered as one of the most challenging periods in Santorini’s recent history and underscores the vulnerability of island communities to environmental catastrophes.
