The hillfort Háj in Sedliacka Dubová, dist. Dolný Kubín was discovered on LIDAR’s photo as part of the international police action so called “PANDORA VI”. In 2021, a non-destructive prospection and a detailed detector survey of the fortified area, including two survey trenches, took place by the authors of the paper in cooperation with the SEPTENTRIO Association. There was found a collection of several bronze, iron and ceramic artefacts, which can be dated to various periods from prehistory (younger stage of the Hallstatt period, La Tène period) to medieval and modern times.
