Himmelsberga, in the centre of the island, is home to Olands Museum, an open-air museum of art and cultural history. It centres around a well-preserved linear village with eighteenth and nineteenth century farms. The interiors of the houses show how life was once lived, and pigs, chickens and sheep are kept in the grounds. A shop sells crafts and books about Oland.

Next to the museum is a gallery showing work by local artist. South of Himmelsberga, Gardslosa Kyrka is one of the most interesting churches on Oland. It dates from the mid-thirteenth century and has excellent limestone murals, a beautiful votive ship and a seventeenth century pulpit.

Oland’s best preserved row of windmills can be seen in Lerkaka, just to the south of Himmelsberga. The interesting Lerkaka Linmuseum shows how linen is made.
