Crown of Bolesław I the Brave in the context of "Fleur-de-lis"

Regalia (/rəˈɡeɪliə, -ˈɡeɪljə/ rə-GAY-lee-ə, -⁠GAYL-yə) is the set of emblems, symbols, or paraphernalia indicative of royal status, as well as rights, prerogatives and privileges enjoyed by a sovereign, regardless of title. The word originally referred to the elaborate formal dress and accessories of a sovereign, but now it also refers to any type of elaborate formal dress. The word stems from the Latin substantivation of the adjective regalis, "regal", itself from rex, "king". It is sometimes used in the singular, regale.

The only surviving original piece of the Polish crown jewels (Polish: Polskie klejnoty koronne) from the time of the Piast dynasty is the ceremonial sword Szczerbiec. It is currently on display along with other preserved royal items at the Wawel Royal Castle Museum in Kraków.

Several royal crowns were made, including several during the 16th century, a "Hungarian Crown", a "Swedish Crown" used by the Vasa kings, and others that were subsequently lost or destroyed. The crown regalia used by the Saxon kings, and some remainders of older Polish monarchs which were appropriated by king Augustus II, also the Elector of Saxony — like a cup of Queen Jadwiga so-called roztruchan, and the magnificent scale armour, so-called karacena, of King John III Sobieski — are today on display in the Grünes Gewölbe and the Rüstkammer in Dresden, Germany.
