The Porāni burial ground consists of about 30 burial mounds. Visual signs of the burial mounds have largely been lost and at the present thay are marked by slight elevations. Excavations have revealed that the burial mounds are cremation graves in which the ashes of the deceased, accompanied by grave goods, were laid to rest under the central section of the mound. The finds and the style of the burials are typical of Scandinavian burial grounds of the time. Based on the finds typology of the artefacts accompanying the deceased, the burial ground`s period of use is dated to the 7yh - 9th century.

Therefore the sites of Grobiņa archaelogical ensemble are included in the transnational serial nomination "Viking age sites in northern Europe" to UNESCO`S world heritage list.
