Lange Anna, Tall Anna, is a 47-metre sea stack of red sandstone at the northern tip of the German North Sea island of Heligoland, about 1 km from the island's town. Its local name means the Northern Stack. It resembles famous sea stacks in Britain and was declared a natural monument in 1969. Weather and sea are wearing it away fast, and it was decided that any effort to preserve it could only slow the process, so it has been left to its fate. Experts see a real risk that its upper two thirds will collapse, because of an unstable layer of sand 16 metres above sea level. The slender red stack stands apart from the island's towering red cliffs, banded with horizontal layers, with a stone sea wall around its base and large numbers of white seabirds nesting on the cliffs. Blue sea stretches to the horizon all around. Visitors walk the clifftop path to viewpoints opposite the stack; climbing it is not allowed, and it can only be seen from a distance. The island is reached by ferry from the German mainland, and the wind is strong on the cliffs, so bring a jacket.
