The lighthouse at Rubjerg Knude, Denmark

It was build some hundred meters from the shore around year 1900, but the ferocious sea has eaten its way into the sand cliffs and now standing just a few meters from the edge of the cliffs the lighthouse will fall into the ocean in few years. Being a huge tourist attraction plans are being discussed to take down the lighthouse brick by brick and raise it again further on land. It will probably be taken down anyways for safety reasons.
