Byrum's raukar, Nature reserve on western shore of Öland, Sweden.
Byrum's raukar is a nature reserve on the western coast of Öland, a Swedish Baltic island, made up of a series of freestanding limestone columns along a stretch of shoreline. The columns stand directly on the beach, some rising from shallow water and others from the rocky shore, all shaped by centuries of wind and wave erosion.
Around 490 million years ago, this part of what is now Sweden lay beneath a shallow tropical sea where coral reefs grew during the Ordovician period. When the sea withdrew, the reef material was left behind and slowly carved by erosion into the columns visible on the shore today.
The word "raukar" comes from the local dialect and refers specifically to these tall, weathered limestone columns found along the Baltic coast. Visitors often notice how each column has a different shape, some wide and flat at the top, others thin and pointed, giving the beach a look unlike any other shoreline.
The reserve sits close to the village of Byrum and is easy to reach by car, with parking areas near the site. Arriving earlier in the day gives visitors more time to walk along the shore and see the columns without crowds.
This type of limestone column is found only on the Swedish Baltic islands, and the Byrum shoreline is one of the densest concentrations on Öland. What many visitors do not realize is that some columns normally sit below the waterline and only become visible when the water level drops, hinting that the formation extends further into the sea.
