Salme river here marks the place of the strait that phased out about 2000 years ago. The peninsula ends with the Sõrve neck and following islets in Irben Strait. The peninsula was first mentioned in 1234 by the name Sworve. The history of the light houses on the island goes back to the year 1646 when the governor general of Livonia, Gabriel Oxenstierna, demanded there must be one. "Must end this run on the rocks," he might have thought which makes one think about all the secret wrecks still there in the bottom of the sea.
