Thera is a volcanic island located in the Aegean Sea, part of the Cyclades archipelago in Greece. It is known for its stunning cliffs, beautiful sunsets, and unique geological features. The island is also famous for its archaeological sites, particularly the ancient city of Akrotiri, which was preserved under volcanic ash after a massive eruption around 1600 BCE. The eruption of Thera is one of the largest in recorded history and had significant effects on the surrounding region. It is believed to have contributed to the decline of the Minoan civilization on the nearby island of Crete. Today, Thera attracts tourists for its picturesque views, rich history, and vibrant culture.
