You can learn more about Swedish culture at The New Sweden Historical Society, which contains three floors of memorabilia and artifacts housed in an exact replica of the colony's original 1870 Kapitoleum, or capitol (the original burned in 1971). Next door, you can visit a Swedish gift shop at the Capitol Hill School, the last remaining of nine original one-room schoolhouses. Behind these buildings, you'll find a monument listing the original settlers.
In New Sweden, you can also see a concert at the W.W. Thomas Memorial Music Bowl at Thomas Park, named for the man who led the first settlers from Sweden to New Sweden in 1870. To learn about the colony's early buildings, you can visit the circa 1870s Larsson/Ostlund Log House, the circa 1900 Lars Noak Blacksmith and Woodworking Shop, and the 1871 Gustaf Adolph Evangelical Lutheran Church. At the Stockholm Historical Society Museum, you'll find a wall of ancestors exhibit, including a photo of Stockholm's first settlers, Alfred and Brita Swenson.
In June, you can help Maine's Swedish community celebrate its heritage during the Midsommar Festival. You can listen to traditional Swedish music, eat traditional Swedish foods, and watch costumed children dance around the Maypole.
