Lange Anna

Lange Anna is a freestanding sea stack made of red sandstone that rises from the water off the northwest coast of Helgoland. The formation stands alone in the sea and displays the characteristic reddish rock layer found throughout the island.

The formation was originally connected to the main island by a natural arch until it collapsed in 1860. Since then, the structure has stood freely in the sea and continues to develop as an independent geological feature.

Local residents refer to the formation as Nathurn Stak in Frisian language, while the German name Lange Anna stems from a tale about a tall woman at a nearby café.

A walking path along the cliff edge leads to several viewing points where you can observe the formation from different angles. The trail runs above the steep coastline and offers open views over the water throughout.

The base received concrete reinforcement in the late 1970s after erosion had created a hollow space beneath the structure. This work continues to protect the formation from further undermining by waves and tides.
