Ailsa

Ailsa is a small, volcanic island located in the Firth of Clyde, off the coast of Scotland. It is the southernmost of the islands in the Firth of Clyde. The island is approximately 3.2 kilometers long and 1.6 kilometers wide at its widest point. Its highest point is Ailsa Craig, which reaches 340 meters above sea level.

The island is known for its dramatic cliffs and is a haven for seabirds, particularly gannets and puffins. It is a designated Site of Special Scientific Interest and a Special Protection Area due to its significant bird populations. Historically, Ailsa was used as a refuge and a stronghold. Its strategic location made it a useful defensive position.

Ailsa Craig is famous for its granite, a hard, fine-grained rock that has been quarried for centuries. This granite has been used to produce curling stones, with the island's stone considered among the best in the world for this purpose. The quarrying operations have significantly shaped the island's landscape.

In recent history, Ailsa has been uninhabited, though it has been visited by tourists and birdwatchers. Ownership of the island has changed hands over the years. Its unique geological formation, ecological importance, and historical significance make Ailsa a notable feature of the Scottish coastline.
