As of 2026, every European country except Vatican City and San Marino has territory on islands, including major ones like the United Kingdom, Greece, and Italy.
Even landlocked Switzerland controls a tiny island in Lake Maggiore—mostly used for cultural events. Then there’s Denmark, which governs Greenland and the Faroe Islands (both technically North American but politically European). Honestly, this is the best way to see how interconnected these nations really are.
What country in Europe has lots of islands?

Finland lands third with 178,947 islands, sprinkled across the Gulf of Bothnia. These numbers shift slightly each year thanks to coastal erosion and rising sea levels.

Lesotho is entirely within South Africa. Vatican City sits inside Rome, Italy. San Marino is tucked into Italy’s Apennine Mountains. Enclaves are rare these days—modern borders have mostly erased them. There are a few semi-enclaves, like Büsingen am Hochrhein (Germany) inside Switzerland, but they don’t count as full enclaves.
What is the largest exclave in the world?
As of 2026, Alaska is the largest exclave in the world, separated from the contiguous United States by Canada.
At 1,723,337 km², it’s nearly one-fifth the size of the rest of the US. Bought from Russia in 1867 and admitted as a state in 1959, its isolation has shaped its culture and ecology. Denali, North America’s highest peak, towers over its rugged landscape. Despite the distance, Alaska is fully tied to the US economy and defense.
