Basiluzzo

Basiluzzo is a small, uninhabited islet in the Aeolian Islands, an archipelago off the northern coast of Sicily, Italy. It is the easternmost of the islands and part of the Lipari municipality. Basiluzzo is essentially a volcanic plug, a solidified core of lava that once filled the vent of a volcano. Its geological composition is primarily basaltic.

The islet is roughly trapezoidal in shape and covers an area of approximately 0.3 square kilometers (0.12 square miles). Its coastline is rugged and rocky, and it is largely devoid of vegetation, supporting only sparse Mediterranean scrub.

Basiluzzo is known for its clear waters, making it a popular destination for scuba diving and snorkeling. The seabed around the islet contains Roman-era archaeological remains, including the submerged ruins of a Roman villa and associated structures, providing insight into the island's past use.

The islet is also a part of the Aeolian Islands UNESCO World Heritage Site, recognized for its outstanding volcanic features and significance in the study of volcanology. While uninhabited, Basiluzzo contributes to the biodiversity and natural beauty of the Aeolian archipelago.

Despite its small size, Basiluzzo plays a vital role in the overall ecosystem and historical narrative of the Aeolian Islands.
