 Monaco features a heraldic crown on its coat-of-arms, but does not possess any crown jewels or regalia per se.The Crown Regalia, or crown jewels, of Norway are together with some other old treasures on permanent display in an exhibition at the Archbishop's Palace next to the Nidaros Cathedral, in Trondheim.The only surviving part of the Polish Crown Jewels is from the Piast dynasty and consists of the coronation sword known as the Szczerbiec.
