Grotte marine di Marettimo

Marettimo’s limestone coast is indented by sea caves, from the Grotta del Cammello near the harbour to the Grotta Bombarda on the island’s outer coast. Their forms reflect the action of the sea on the island’s Triassic dolomite and limestone, within the protected waters of the Egadi Islands.

Why it matters

Marettimo is known for its many sea caves, a distinctive feature of the island’s rugged coast. The Area Marina Protetta delle Isole Egadi recognises protected marine habitats and species in these waters, including the monk seal. Archaeological discoveries at Grotta della Pipa also point to human activity along this coast.

What to notice

The caves have varied forms and names. Grotta del Cammello is associated with a rock formation resembling a camel; Grotta del Tuono with the sound of swell within the cave; and Grotta Perciata with an opening through the rock. Stalactites and stalagmites give Grotta del Presepe its name, while Grotta Bombarda is noted for its larger chamber. Grotta della Pipa lies near Scalo Maestro.

Context and history

Marettimo’s sea caves formed as the sea eroded the island’s Upper Triassic dolomite and limestone. The island is part of the Egadi archipelago, whose waters are included in the Area Marina Protetta delle Isole Egadi. The islands were known in antiquity as Hierà Nèsos, and the surrounding sea was the setting of the Battle of the Aegates in 241 BC, which ended the First Punic War.
