The Grobiņa archaeological complex includes multiple Curonian and Scandinavian first millennium burial sites, dwellings and hill-forts. Until now, more extensive research has been carried out on the Scandinavian barrow and flat burial fields, and on a small scale on the Curonian burial grounds; but less attention has been paid to examining dwellings. Excavation materials have only been partly publicised. During the latest research, the habitation period of the hill-fort has been determined, and the dwelling areas on both banks of the River Ālande have been determined and specified. Multiple issues have been overviewed in relation to Grobiņa archaeological site complex: the population in the Grobiņa region during the middle and latter part of the first millennium; and the interaction between Curonian and Scandinavian cultures.
