The island's architecture is a mix of ancient and modern styles. The old town of Fira, the capital of Santorini, is built on the rim of the caldera and features narrow streets, whitewashed houses, and blue-domed churches. The houses are built into the cliffside, with steep stairs and winding alleys that offer breathtaking views of the caldera.

The island's landscapes are equally stunning. The beaches are white-sand and turquoise, surrounded by towering cliffs and crystal-clear waters. The most famous beach is Red Beach, which is accessible only by boat.
