diamonds rather than pearls. Both crowns, and other royal insignia, are located in Rosenborg Castle in Copenhagen. The blazon in heraldic terms is: Or, three lions passant in pale azure crowned and armed Or langued gules, nine hearts Gules. This insignia is almost identical to the coat of arms of Estonia and the greater coat of arms of Tallinn which can both be traced directly back to King Valdemar II and the Danish rule in northern Estonia in 1219–1346. The main differences are as follows: In the Danish coat of arms the lions are crowned, face forward, and accompanied by nine hearts. In the Estonian coat of arms, the "leopards" still face the viewer, they are not crowned, and no hearts are present. The coat of arms of Tallinn resembles the Estonian arms, but the leopards in the former arms are crowned with golden crowns similar to the ones in the Danish arms. It shows great similarities with the contemporary insignia of England's Richard the Lionheart and the current arms of the German state of Baden-Württemberg. The Danish coat of arms has also been the inspiration for the coat of arms of the former Duchy of Schleswig, a former Danish province (two blue lions in a golden shield). The hearts of the coat of arms also appear in the coat of arms of the German district of Lüneburg. Royal Coat of Arms The Royal Coat of Arms is more complex. The current version was established by royal decree 5 July 1972. It is much simpler than previous versions. The shield is quartered by a silver cross fimbriated in red, derived from the Danish flag, the . The first and fourth quarters represent Denmark by three crowned lions passant accompanied by nine hearts; the second quarter contains two lions passant representing Schleswig, a former Danish province now divided between Denmark and Germany; the third quarter contains a total of three symbols. The Three Crowns are officially interpreted as a symbol of the former Kalmar Union. The silver ram on blue represents the Faroe Islands and the similarly coloured polar bear represents Greenland. The centre escutcheon, two red bars on a golden shield, represents the House of Oldenburg, the former royal dynasty that ruled Denmark and Norway from the middle of the fifteenth century. When the senior branch of this dynasty became extinct in 1863, the crown passed to Prince Christian of
