Crown jewels

Crown Jewels are the objects of metalwork and jewellery in the regalia of a current or former monarchy. They are often used for the coronation of a monarch and a few other ceremonial occasions. A monarch may often be shown wearing them in portraits, as they symbolize the power and continuity of the monarchy. Additions to them may be made, but since medieval times the existing items are typically passed down unchanged as they symbolize the continuity of the monarchy.
Emperor of Austria

The Emperor of Austria was the ruler of the Austrian Empire and later the Austro-Hungarian Empire. A hereditary imperial title and office proclaimed in 1804 by Holy Roman Emperor Francis II, a member of the House of Habsburg-Lorraine, and continually held by him and his heirs until Charles I relinquished power in 1918.
Holy Crown of Hungary

The Holy Crown of Hungary, also known as the Crown of Saint Stephen, was the coronation crown used by the Kingdom of Hungary for most of its existence; kings have been crowned with it since the twelfth century. The Crown was bound to the Lands of the Hungarian Crown. No king of Hungary was regarded as having been truly legitimate without being crowned with it. In the history of Hungary, more than fifty kings were crowned with it, up to the last, Charles IV, in 1916.
Archduke
Archduke was the title borne from 1358 by the Habsburg rulers of the Archduchy of Austria, and later by all senior members of that dynasty. It denotes a rank within the former Holy Roman Empire (962–1806), which was below that of Emperor and King and above that of (debatably) a Grand Duke, Duke and Prince.
Imperial Crown of the Holy Roman Empire

The Imperial Crown of the Holy Roman Empire was the hoop crown of the Holy Roman Emperor from the 11th century to the dissolution of the Holy Roman Empire in 1806. The crown was used in the coronation of the King of the Romans, the title assumed by the Emperor-elect immediately after his election. It was made in the late 10th or early 11th century. Unlike many other crowns, it has an octagonal rather than a circular shape, and is constructed from eight hinged plates. The plate in the front of the crown is surmounted by a cross, with a single arch linking it to a plate at the rear of the crown. The crown is kept in the Imperial Treasury at the Hofburg in Vienna, Austria.
Globus cruciger

The globus cruciger, also known as "the orb and cross", is an orb surmounted by a cross. It has been a Christian symbol of authority since the Middle Ages, used on coins, in iconography, and with a sceptre as royal regalia.
Archducal hat

The archducal hat is the insignia of the Archduchy of Austria, mostly apparently symbolic and used in the heraldry and some portraits of Austrian archdukes rather than routinely worn. One late example is kept in Klosterneuburg Monastery.
Imperial Crown of Russia
The Imperial Crown of Russia, also known as the Great Imperial Crown, was used by the monarchs of Russia from 1762 until the Russian monarchy's abolition in 1917. The Great Imperial Crown was first used in a coronation by Catherine the Great, and it was last worn at the coronation of Nicholas II. It was displayed prominently next to Nicholas II on a cushion at the State Opening of the Russian Duma inside the Winter Palace in St. Petersburg in 1906. It survived the 1917 revolution and is currently on display in Moscow at the Kremlin Armoury's State Diamond Fund.

Imperial Crown of Austria
The Imperial Crown of Austria was made in 1602 in Prague by Jan Vermeyen as the personal crown of Holy Roman Emperor Rudolf II, and therefore is also known as the Crown of Emperor Rudolf II. The crown was used as a private crown of the Holy Roman Emperors and Kings of Hungary and Bohemia from the House of Habsburg. In 1804 it became the official crown of the newly constituted Austrian Empire. After 1867 it remained the imperial crown of the Cisleithanian part of the Austro-Hungarian Empire until 1918.
Polish Crown Jewels
The only surviving original piece of the Polish Crown Jewels 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.
Regalia of Serbia

Serbia, like most former monarchies of Europe, has had crowns once worn by its rulers. The various Serbian principalities and kingdoms were organised around a number of different royal dynasties. Many of these invested in symbols of royalty which has led to a number of distinctive crowns, jewels and other treasures of incredible wealth surviving to the present day. As far as is known, there are four royal crowns once worn by Serbian kings or princes that have survived to the present day, of which just one is kept in the modern Republic of Serbia today.
Vienna Coronation Gospels

The Vienna Coronation Gospels, also known simply as the Coronation Gospels, is a late 8th century illuminated Gospel Book produced at the court of Charlemagne in Aachen. It was used by the future emperor at his coronation on Christmas Day 800, when he placed three fingers of his right hand on the first page of the Gospel of Saint John and took his oath. Traditionally, it is considered to be the same manuscript that was found in the tomb of Charlemagne when it was opened in the year 1000 by Emperor Otto III. The Coronation Evangeliar cover was created by Hans von Reutlingen, c. 1500. The Coronation Evangeliar is part of the Imperial Treasury (Schatzkammer) in the Hofburg Palace in Vienna, Austria.
Archduchy of Austria

The Archduchy of Austria was a major principality of the Holy Roman Empire and the nucleus of the Habsburg Monarchy. With its capital at Vienna, the archduchy was centered at the Empire's southeastern periphery.
Imperial Sword

The Imperial Sword is one of the four most important parts of the Imperial Regalia (Reichskleinodien) of the Holy Roman Empire. During a coronation, it was given to the emperor along with the Imperial Crown (Reichskrone), Imperial Sceptre (Reichszepter), and the Imperial Orb (Reichsapfel). All four parts of the Imperial Regalia are displayed in the Imperial Treasury at the Hofburg Palace in Vienna, Austria.
Coronation of the Holy Roman Emperor

The Coronation of the Holy Roman Emperor was a ceremony in which the ruler of Western Europe's then-largest political entity received the Imperial Regalia at the hands of the Pope, symbolizing both the pope's right to crown Christian sovereigns and also the emperor's role as protector of the Roman Catholic Church. The Holy Roman Empresses were crowned as well.

The Imperial Treasury at the Hofburg Palace in Vienna, Austria contains a valuable collection of secular and ecclesiastical treasures covering over a thousand years of European history.

The Imperial Treasury is affiliated with the Kunsthistorisches Museum, and houses in 21 rooms a collection of rare treasures that were compiled by the Imperial House of Habsburg over the course of centuries, including the Imperial Crown, Orb, and Sceptre of Austria, and the Imperial Regalia of the Emperors and Kings of the Holy Roman Empire, including the Imperial Crown of the Holy Roman Empire.
