This paper deals with hill-forts located on and directly south of Selaön, in the center of Mälardalen, Södermanland, dated to the late roman period and the migration period. Of special interest is differences and similarities between the forts when it comes to their morphology and the hills where they were built. Furthermore, their landscape has been examined and I have tried to put the hill-forts in relation to any iron age settlements.
