The seastack area in Langhammar is without a doubt one of Gotland’s most beautiful!
On the beach slope above Klajvika are about 50 seastacks, some of which are more than 8 meters high and shaped like pillars.
During the Silurian period (444 – 416 million years ago) Sweden was quite close to the equator, which has resulted in the Silurian bedrock on Gotland being the remains of several large reefs. The bedrock on Gotland testifies that the sediments (which then came to form the calcareous bedrock) were deposited in a shallow tropical sea. The mighty seastacks have been formed by erosion – wind, water, waves, gravitational movements and living organisms.
Seastacks are called ”raukar” in swedish and areas of many of them are called ”raukområde”.
At Langhammars you will find the largest and highest seastacks and on the road out to Langhammars seastack area you will find a landscape that reminds you of the pictures you have seen from the first steps on the moon by Neil Armstrong.
