Église Sainte-Radegonde is a well-maintained 6th-century church with a beautiful Roman tower. Established as a mortuary chapel, it is home to the tomb of Queen Radegonde, who died in 587 AD, and was constructed in Romanesque style.

The Långe Jan lighthouse — 'Tall John' — first cast its light over the Baltic waves on November 1, 1785. Rising from the craftsmanship of, perhaps, Russian prisoners of war, it stands as a beacon of history and maritime safety on Öland's southernmost point. Initially measuring a soaring 36 meters and requiring a 197-step ascent, it now proudly stretches to 41.6 meters, claiming the title of Sweden's loftiest lighthouse. Once cradling an open flame against the Nordic sky, Långe Jan has seen transformations from bare stone, borrowed from a bygone chapel, to a whitewashed pillar with a distinguishing black band. Surrounded by the thriving Ottenby bird station, Långe Jan's legacy is as enduring as the coastal winds, welcoming visitors each summer to scale its heights and embrace a panoramic sweep of sea and sky.

This cave is a spectacular jewel of natural phenomena. It was discovered in 1840, and opened to the public in 1908. An indeed unusual excursion into what looks like another world.
