Santorini is a beautiful island in the Aegean Sea, part of the Cyclades group of islands in Greece. Known for its stunning sunsets, white-washed buildings, and blue-domed churches, it attracts many tourists each year. The island was formed by a volcanic eruption thousands of years ago, which created its unique caldera and dramatic cliffs. The main towns on Santorini include Fira and Oia, both offering breathtaking views of the sea. Visitors can explore ancient ruins, relax on unique beaches with black or red sand, and enjoy delicious Greek cuisine. Santorini is also famous for its local wines, particularly the Assyrtiko variety.
