Solliden is the summer residence of the Swedish royal family, which they visit several times a year. Commissioned by Queen Victoria, on the advice of her doctor Axel Munthe, and with Mediterranean influences, the palace was completed in 1906. Munthe was of the opinion that Öland’s abundant sunshine and oxygen-rich air would improve her health, and to this day the royals are happy to enjoy Öland’s sun! Solliden Palace is open to visitors throughout the summer months. Visitors have free access to most of the parks. Café, shop and a pavilion with exhibitions.

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.
