Origin of the name

The name is derived from a small hunter's lodge located near the present lake. In historical records documenting fishing grounds on Djurgården during the 17th century, the lodge is unintelligibly called ''Isbla''. The same lodge also gave name to a bay, Isbladsviken. Most Stockholmer's today are likely to interpret the name as ''Is-blads-kärret'' ("The Ice Leaf Marsh").
