Byrum's raukar, Nature reserve on western shore of Öland, Sweden.
Byrum's raukar is a nature reserve on Öland's western coast featuring roughly 120 limestone stacks scattered across a 600-meter stretch of shoreline. These stone pillars were formed from an ancient coral reef and create an unusual landscape along the beach.
This area was a shallow tropical sea roughly 490 million years ago when coral reefs formed during the Ordovician period. As the ocean receded over time, the reef structures were exposed and shaped by erosion into the stone columns we see today.
The site draws geologists and nature enthusiasts who come to examine the fossil records and ancient reef composition visible in the formations. Visitors can observe how the landscape tells a story of transformation across deep time.
The reserve is easy to reach with two parking areas located near the site, both accessible quickly from Byrum village. When one lot fills up, additional parking spaces are available just a short walk away.
These stone pillars exist only on Swedish Baltic islands, making them a distinctive feature of the region. The Byrum area preserves the sole known examples of this formation found on the entire island.
