For most of recorded history, the island of Wangerooge has been moving. Not by much - a few meters a year, sometimes more, sometimes less - but consistently east, on a slow current of erosion that gnawed at its western flank and dropped fresh sand on its eastern tip. The water doing the eroding has a name. It is the Harle, also called the Harle Seegatt, the tidal strait that runs north-to-south between Wangerooge and the island of Spiekeroog. For centuries it was the most patient bulldozer in the German Bight. In the 1960s, engineers built a wall to make it stop.

The Harle Seegatt threads its way through the gap between Spiekeroog to the west and Wangerooge to the east, draining the Wadden Sea behind them into the open North Sea on each falling tide. The main channel splits as it approaches the islands - one branch, the Alte Harle, runs t...

Wangerooge drifts. Of all the East Frisian Islands, it has historically moved farthest and fastest, and the Harle is the reason. The strait's currents eroded the western tip of the island with a steadiness that no village or pier could outlast. Old maps, laid one over another, sh...

The walking stopped, mostly, in the 1960s. The Wilhelmshaven authorities built a concrete barrier along the western shore of Wangerooge and a system of groynes - long fingers of rock running out into the water - designed to break the current and trap sand. The longest groyne reac...

More recently, the expansion of the harbor area on Wangerooge has changed the line on the chart. Niedersachsen Ports - the regional ports authority - now manages the transition zone between the inner harbor and the open strait, in a channel known officially as the Wangeroog Anste...
