Bolmsö is an island located in lake Bolmen near Växjö in Småland.
It presents 530 ancient remains, including dolmens and cobble-clad graves in various forms, especially large triangular ones.
In the Hervarar saga, it is related that Arngrim and his twelve wild sons, who fought against Hjalmar, lived on Bólmr and it is believed to refer to Bolmsö.
The identification is supported by Saxo Grammaticus who described Arngrim as a Swedish berserker.
