Here's a short but interesting article about a German goverment department in the Pankow district of Berlin that still holds thousands of artefacts from the 3rd Reich era.
Some belonged personally to senior members of the party, pieces supposed to be of Goring's train set and artefacts he kept at Karinhall, whilst others are pieces of furniture and carpets etc, from party buildings like the Reichs Chancellory. But the largest amount of items are those things like art, paintings, sculpture, books, manuscripts and rare coins looted from the Jews and countries that the Nazies invaded.
This goverment department has for years been trying to reunite many of these artefacts to their rightful owners or latter day relatives, others have been given to museums, but as it says in the article, this has proved extremely difficult, and in most cases will never happen and some articles may eventually be auctioned off.
Anyway as I said, a short but interesting article, it's a shame they don't put it all on display, I for one would go to see it!
