Until the Minoan eruption of the prehistoric times that created the caldera, it was part of the island of Strongyli, whose circular contour is now completed together with the islands of Thira (Santorini) and Aspronissi. Thirassia was separated from Strogyli during the catastrophic eruption of the volcano in 1600 BC.
The historian Pliny mentions that in 237 BC. Thirassia had seceded from Thera after an earthquake. Ptolemy mentions that Thirasia was a city in which important prehistoric remains of the Cycladic civilization were found and that in all historical periods it followed the fate of Thera. In 1397, the Duke of Naxos, Francesco I Crispo, is considered to have assigned it to his son Marko I together with Io.
By 1866, the mines in Therasia and Thera were in full operation as Theran land was being exported to Egypt, where the Suez Canal was being built. Some workers, randomly digging in the mine of Nikolaos Nomikos-Spyridon Alafouzou, discovered remains of an ancient building, clay vessels and a human skeleton. The doctor and MP Nikolaos Nomikos together with Alafouzos took care of the excavation of the building, while related articles were published in magazines and newspapers.
Due to the activity of the volcano in the period 1866-1870, scientists from all over the world had arrived in the area. Among them was the French volcanologist Ferdinand Fouquet, who in 1867 excavated in Therasia and studied the remains of the buildings and various other findings. The settlement in Thirasia was dated to the Late Bronze Age and these findings gave the impetus for the excavations at Akrotiri and other parts of Thira.
