The Holy Crown was made of gold and decorated with nineteen enamel
pantokrator pictures (Greek, meaning "master of all") as well as semi-precious stones, genuine pearls, and
almandine. It has three parts:
abroncs (rim, hoop) (
corona graeca),
keresztpántok (cross straps) (
corona latina), and the cross on the top tilted at an angle. Four hanging pendants (
pendilia) dangle from chains on each side of the diadem and one in the back. The crown has no
monde. Peer-reviewed studies published in 2024–2025, applying archaeoengineering investigative methods, concluded that the Holy Crown was produced as a uniformly planned and assembled structure, whose primary and structurally determining element is the cross-strap system. Through the analysis of manufacturing sequence, applied techniques, geometric reproducibility, and failure mode and effects analysis (FMEA), an independently verifiable technical method of interpretation was established for the crown. One of the technical conclusions is that the hoop of the crown cannot be interpreted as a crown originating from Emperor Michael VII Doukas and later transferred to King Géza I of Hungary, as the structural and geometric relationships do not support this interpretation on technical grounds.
Corona graeca The (rim, hoop) ("Greek Crown") is 5.2 cm wide with a diameter of 20.5 cm. The two aquamarine stones with cut surfaces on the back of the diadem were added as replacements by
King Matthias II (1608–1619). The enamel picture on the front depicts
Christ Pantokrator. On the rim to the right and left of Jesus are pictures of the archangels
Michael and
Gabriel, followed by half-length images of the Saints
George and
Demetrius, and
Cosmas and Damian. on the of the Holy Crown of Hungary In the arched frame on the back of the diadem
Emperor Michael VII Doukas (1071–1078) is depicted. Below it to the left is the half-length picture of "Kon. Porphyrogennetos", this probably being either Emperor Michael's brother and co-emperor
Konstantios Doukas or of his son and heir
Constantine Doukas, both having been
born in the purple. To the right there is a picture of the Hungarian King Géza I (1074–1077), with the
Greek inscription: (, meaning "
Géza I, faithful
kralj of the
land of the Turks"). The contemporary Byzantine name for the Hungarians was "Turks", This view is confirmed by the fact that Grand Prince Géza is depicted on the without a crown, although carrying a royal sceptre.
Corona latina The (cross straps) ("Latin Crown") is made of four 5.2-cm-wide gold strips welded to the edge of a square central panel (7.2 × 7.2 cm); the strips are usually assumed to have been originally made for some other object, and adapted for the crown. It is not an independent object, as it has no function alone. It was designed to be attached to the top rim of the and provides a dome-shaped top. The inscription on the pictures of the saints and the style of their lettering suggest the date when they were made. Amidst the antique-style capital letters, the T in Thomas and the second U in Paulus are formed in the style characteristic of the Latin letters used on Byzantine coins, a practice abandoned in the middle of the 11th century. They may have decorated a reliquary box or a portable altar given to István I by the pope, or possibly the
treasure binding of a book. It is also possible, although it cannot be verified, that István I received a crown as a gift from one of the popes, reciprocating hishistorically documentedgifts. The picture of the apostles (Peter, Paul, James, John, Andrew, Philip, Bartholomew, Thomas), however, based on their style, cannot be dated to around 1000. It is considered to be of
Romanesque style, and created by Roman workshop in the middle of the 11th century. In order to get it to fit into its new role the apostles at the bottom of each of the four arms of this asterisk were cut off before it was very crudely attached to the inside of the to transform this Byzantine open crown into a closed crown (i.e., the type of crown proper to the autocrat, the senior emperor or monarch in Byzantine imperial protocol) and to provide a base for the reliquary cross at its summit (see ). Recently, Croatian archaeologists M. Ilkić and D. Filipčić proposed thesis that the
crown of Zvonimir, the last native Croatian king and which was once believed to have disappeared, is actually the , as "the only plausible place where Zvonimir's crown could end up, while maintaining the legitimacy of the coronation of new Hungarian-Croatian kings and respecting the tradition and legality of the coronation of Béla IV's predecessors, is within the Hungarian crown".
Cross , showing the cross in vertical position The cross is attached to the crown in a rough manner, rising from the midriff of Christ in the central enamel plaque at the top of the crown. This addition might have been made during the 16th century. The cross was knocked crooked during the 17th century when the crown was damaged, possibly by the top of the iron chest housing the insignia being hastily closed without the crown having been placed in it properly. The cross has since been left in this slanted position, and is now typically depicted as such. Éva Kovács suggests that the present plain cross on the top of the crown is a replacement of an original double-barred reliquary cross containing three pieces of the
True Cross and that it was the presence of the True Cross in the Holy Crown which made it holy. She states that "Szabolcs Vajay called to my attention a strange incident in the crown's history which had completely escaped everybody's attention. Before Queen
Isabella handed over the regalia to
Ferdinand in 1551, she broke the cross off the crown's peak for her son, John Sigismund. According to a contemporary Polish chronicler, John Sigismund wore this cross on his chest till the end of his life, "... because he who possesses this cross will again come into possession of the missing parts which, subjected to the power of the cross, had belonged to it". Later, the cross became the property of Sigismund Bathory who, persuaded by his confessor, bestowed it on Emperor Rudolf II. This was reported by an Italian envoy in Prague who also told the Isabella-John Sigismund story." She also notes that "Several small fragments of the True Cross were in possession of the Arpad dynasty. As a point of interest, it is precisely the smallest ones, those set into the cross on the chest, that are attributed to St. Stephen. About a tiny fragment of the True Cross, a Russian chronicler recording King Geza II's campaigns wrote that it had been the holy king's property and, despite its small size, it was a relic of great force. We are, perhaps, not off the track when surmising that the Hungarian crown was holy because it had once been reinforced with a fragment of the victory-bringing relic. . . we know quite few reliquary crowns. To mention but the most obvious example, let us cite Charles I's crown provided with a cross containing a thorn relic." Later, it was the Crown itself, rather than the St. Stephen's cross reliquary that came to be regarded as holy through its traditional association with St. Stephen. Éva Kovács further notes in this regard the early use of the patriarchal or double-barred cross and crown in the ancient Hungarian royal coat of arms. Since reliquary crosses frequently take such a double-barred form, the use of a patriarchal cross in the royal arms would be a direct reference to and representation of this royal relic. This association between the crown and this royal relic would also help to substantiate the theory that the Holy Crown was always intended to serve its historical role of legitimatizing the position of its wearer as the true divinely appointed king of Hungary.
The crown as a whole crowned with the Holy Crown as the King of Hungary The form of the Holy Crown is identical to that of the
kamelaukion-type crowns with closed tops, as introduced in the Byzantine Empire. The presence of multiple pictures is also typical of Byzantine crowns. When the intersecting bands were added to the
corona graeca during the rule of Béla III, who had been brought up in Constantinople, the bands were decorated just as the
corona graeca was, perhaps with the intention of imitating the Byzantine pattern.
Links to the first Hungarian king, Saint Stephen Beside the using of the intersecting bands of the
corona latina, which probably came from the treasury of St. István, at the time of the creation of the crown there existed further expectation that the coronation insignia would eventually include additional gold works that could be linked to the first, beatified Hungarian king, István. The inscription embroidered onto the coronation mantle indicates with all certainty that István I and Queen Gizella had it made in 1031. The coronation sceptre with the orb at the end can also be dated to the time of St István. On the seals of
Henry II, Holy Roman Emperor, and
Rudolph III of Burgundy, the rulers are holding identically shaped sceptres. Such short-staffed sceptres ending in orbs were not in use as insignia earlier or later. ==The regalia in modern times==
