The settlement complex in Jeziorko is located in the western part of Masurian Lake District, around 3 km north-west from the main road between the towns of Ryn and Giżycko. The site has been widely known since the 17th c. and presumed as one of the most important hillforts of the Early Iron Age and the Middle Ages. The current state of research allows us to qualify it as one of the best examined archaeological sites in central parts of Masurian Lake District. The discussed settlement consists of three main parts. The top of the hill surrounded by ramparts appears to be a main defensive area. on the eastern side, Settlement I covers the characteristic lower part of the hill and it extends to the south where Settlement II is situated. During the 2009 season Settlement I was excavated. Within documented deposits the most interesting finds have been discovered in layers dated back to the early stages of the Early Iron Age. The most characteristic seem to be over a dozen of bronze ornament manufacturing remains together with casting moulds suggesting the existence of a local jewellery workshop. Equally important finds have been recorded within the structures from later phases of the Early Iron Age. Among them we can distinguish vari- ous pottery remains, a bronze spiral ring and iron pins considered to be the traces of influences of the neighbouring Pomeranian and Jastorf Cultures. According to presented research results it can be concluded that the site played a key role in cultural development of the West Balt Barrow Culture in Masurian Lake District being on the one hand one of the largest settlements and on the other hand the trade and production centre.
