Seiser Alm - The meadow by the lake

Seiser Alm (in Italian: Alpe di Siusi) is the largest high-alpine meadow in the world, located in South Tyrol in northern Italy (Alto Adige). It lies at an altitude of approximately 1,800–2,350 meters in the Dolomites and is a UNESCO World Heritage site.

The name comes from Ladin/Tyrolean and roughly means "lake meadow" or "the meadow by the lake" – Seis refers to the nearby village of Seis am Schlern.
