Since many camps and memorials was close to sensitive military areas the government was afraid Soviet spies would visit and wanted to centralize the fallen POWs in one big graveyard on Tjøtta south of Mo i Rana, and so they did, destroying and desecrating the gravesites and memorials the liberated prisoners had made. A few memorials survived, and several more has been restored and maintained by locals and can be visited in the forests.
Many of the campsites is close to roads or trekking routes but is so overgrown and hidden by nature that only the ones with a interest in the subject knows they are there. I love going to these places as they have a eerie ghostly vibe to them. Often the camps was so infested with fleas and sickness that they was burned down and some was used to house Germans as they awaited transport back to their fallen reich. As time went any usable materials was removed by locals but as you ll see there is still lots of traces.
