[1] The museum has been run by a local Swedish-speaking organisation called Hembygdens Vänner I Sjundeå (translates to The Friends of Homeland in Siuntio) since 1965.

[1][5] The main exhibitions in the Fredriksberg school building showcase items to visitors, ranging from prehistory to modern times in independent Finland.

Points of interest include items from the Soviet rental era of Porkkala Naval Base, parts of an 18th-century organ from St. Peter's Church in Siuntio, and dolls from Mona Leo's puppetry.

[6][4] Originally, the museum was located in Fanjunkars croft, which was destroyed after the Second World War during the Soviet rental era of Porkkala Naval Base.

The hill of Krejansberget is situated adjacent to Siuntio Local History Museum, known for Bronze Age burial mounds on top of it.
