When strolling around the city centre it is impossible not to notice this majestic white building and, if you are impressed by its exterior, you should definitely see the spectacular interior decor. Built in 1910 by the architects Jules Voinot and Marius Toudoire, it once represented the city forum and today certainly is one of the main touristic spots, standing in stark contrast to the surrounding buildings. The Grand Post Office also hosts a museum dedicated to the history of Algerian post and telecommunications.

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.

In Skäftekärr, close to Böda in northern Öland, lies an Iron Age village with around 20 well-preserved stone house foundations spread across 10 farms dating from 300–700 AD. At the heart of the Iron Age village are the remains of a chieftain's estate, comprising four house foundations. Adjacent to this historic site, the "new Iron Age landscape" includes a reconstructed version of one of these typical houses and the charred remains of an earlier reconstruction. The park is also home to an impressive collection of approximately 140 different species of trees and shrubs, forming an arboretum. An eco-park center with information about the Böda Eco-park is available on-site, along with Skäftekärr café, hotel, and conference, housed in the majestic main building. For the little ones, a popular obstacle course adds to the day's adventure.
