The vault under the palace´s southern wing has not always housed regalia. The Treasury was inaugurated in these rooms in 1970, following a parliamentary resolution passed in 1969.
Prior to 1970 the regalia were kept under lock and key and could only be viewed on rare occasions.
The regalia are the symbolic objects that The King or Queen are presented with by the Archbishop on coronation day.
The first of the Swedish kings who we can say with certainty was crowned was Erik Knutsson. His coronation took place in 1210. No regalia have been preserved from this time however.
The oldest preserved objects are two swords of state belonging to Gustav Vasa that are exhibited in the Treasury's inner sanctuary. The oldest preserved crown belongs to Erik XIV.
Erik's regalia collection was made for the coronation of Gustav Vasa's oldest son Erik XIV. The coronation took place at the Uppsala Cathedral on June 29, 1561 and was one of the most magnificent ceremonies in Swedish History.
Erik XIV's coronation laid the ground for all future Swedish coronations. During the ceremony the Archbishop read a prayer for each of the regalia. The prayers formulated each object's symbolic meaning.
So it came to be that the crown represented royal honour and dignity and the sceptre represented The King's duty to act and rule over his people, in other words temporal power.
The orb represented spiritual power - that the King, who receives his power from god, shall rein over a large Christian kingdom, which he shall uphold and improve.
The key was said to represent The King's power to keep out the bad, hold in the good and open in times of emergency.
It is this collection of invaluable objects that still nowadays are regarded as The King´s regalia. This means that some of them are used today on ceremonial occasions such as coronations, baptisms, weddings and funerals.
Accordingly, at the The King and Queen´s wedding ceremony in 1976, The King´s Crown was placed on one side of the alter and the Queen on the other.
The country's most recent coronation was Oskar II's in 1873. When he died in 1907, his son and heir to the throne Gustaf V refrained from a coronation ceremony.
Maria Eleonora's crown, made in 1620 is the heaviest in the Treasury. It weighs approximately 2.5 kg . It must be remembered that the bearer had to also wear the rest of the regalia, which were also heavy, as well as a heavy coronation mantle.
This “queen's" crown was used as the country's Royal Crown for four generations from Adolf Fredrik's coronation in 1751 to Karl XIII's death in 1818.
In the year 1751 Lovisa Ulrika's crown was made by Andreas Almgren according Jean Erik Rehn's design. The crown is made of silver and diamonds, completely in line with the prevalent fashion at that time.
Despite its small size, which was also in line with the trend at that time, it contains a total of 695 diamonds! The crown is still seen as the crown of the queen's of Sweden.
At Gustav III coronation in 1772, crowns were also made for the royal siblings. Thereby, Duke Fredrik Adolf as well as Princess Sofia Albertina both received crowns.
A fourth crown was added at a later date and belonged to Hedvig Elisabeth Charlotta, Duke Karl´s consort.
Prince Wilhelm's crown is the latest crown in the Treasury's collection.
It is made by Hallbergs Guldsmeds AB in Stockholm for the declaration of The Princes majority in 1902 at the ceremonious opening of Riksdagen (the Swedish parliament).
The silver baptismal font was commissioned in 1696 - when Karl XI was of the opinion that the new Royal Chapel, in the old palace, was in need of a new baptismal font.
It took all of 11 years to complete and following Gustav III's baptism, almost all of the royal children have been baptised in it.
The baptismal font is still used today, most recently for Prince Oscar's baptism in 2016.
