The day prior to the Opera gala Miss Silvia Sommerlath, then still a foreign citizen, had been awarded the Order of the Seraphim, which she now wore for the first time.
Following the gala performance, the King hosted a supper and dance at Drottningholm for around 200 invited relatives and personal friends.
Early on the morning of the wedding, Erik XIV's and Lovisa Ulrika's crowns had been collected from the Treasury by the Master of Ceremonies and two chamberlains. The crowns were taken to Stockholm Cathedral and placed on dark-blue cushions to the right and left side of the altar respectively.
On the altar was hung an antependium, donated by Axel Oxenstierna's son Johan in 1659. It was brocade with a small floral pattern and decorated with the Oxenstierna and Brahe coat of arms.
The initials, titles and estates of the donor and his wife Margareta Brahe are embroidered on the antependium, which is unique to Stockholm Cathedral and is used for royal ceremonies.
The altar also bore two large candelabras and a crucifix of oak, silver and gold, made in Augsburg and donated by Magnus Gabriel De la Gardie to Queen Kristina on her coronation in 1650.
Stockholm Cathedral was decorated in light colours, with blue delphiniums and pink stock in the castle's abundant flower urns.
Silvia Sommerlath had herself selected the two silver vases standing on the Altar, filled with Queen Silvia's own rose, "Queen Silvia", cultivated by growers especially for the occasion. Queen Louise had donated the vases to Stockholm Cathedral and Silvia was very fond of them.
King Carl Gustaf awaited his bride in the church vestibule, dressed in his admiral's uniform.
The bridal couple walked down the aisle to J.H. Roman's "Sinfonia de Chiesa". Their attendants were Amelie Middelschulte, James Ambler, Helène Silfverschiöld, Hubertus Hohenzollern and Sophie Sommerlath.
In keeping with German wedding custom, the wedding ring, white gold with diamonds, was carried on a cushion by bridesmaid Carmita Sommerlath, daughter of the Queen's brother Ralf Sommerlath.
Her lace veil was an heirloom of the Bernadotte family, passed down from Queen Sofia and worn by the King's mother Princess Sibylla and sisters Princesses Désirée, Margaretha and Christina. The veil had been folded back to form a gossamer cascade and was held in place by the tiara trimmed with myrtle from Crown Princess Margareta's original plant on Sofiero.
Young florist Marlene Pröpster from department store NK had been given the honour of tying the bridal bouquet of orchids, wax flowers, lilies of the valley and myrtle.
The programme for the ceremony was "Festmusik" by Lars-Erik Larsson, the Swedish hymns "I denna ljuva sommartid" and "Herren vår Gud är en konung i makt och i ära", G.P. Telemanns "Wie ist Dein Name so gross" and, as exit music, "Sinfonia D-dur" by J.S. Bach.
Cathedral organist Gotthard Arnér played the organ, while the rest of the music was performed by Swedish Radio's symphony orchestra led by conductor Gustaf Sjökvist.
The quay had been transformed into a flowery meadow. A total of 224 folk musicians from Dalarna conducted by national folk musician Knis Karl Aronsson played "Brudmarsch från Leksand" (Bridal march from Leksand) as the newlyweds walked along the red carpet to the Palace.
At the steps to Logården the Governor of the Royal Palace Sixten Wohlfart welcomed them to the Royal Palace of Stockholm, home of The King and Queen. The bride and groom thanked the attending organisations at a short ceremony in the Inner Courtyard.
The traditional wedding picture was taken by photographer Lennart Nilsson. He took his time over this and the many thousands of Stockholmers gathered on Norrbro and the adjacent streets and squares had a long wait for the bridal couple.
Finally, just as the first raindrops began to fall, King Carl Gustaf and Queen Silvia came out onto the balcony above Lejonbacken. "We are so happy," said the King, lifting the Queen's arm in a radiant gesture.
Magnificent wedding croquembouches, decorated with pink marzipan roses, dominated the table. These had been baked by Operakällaren's master confectioner Dag Öster.
The couple went to Hawaii for their honeymoon, after which they returned for a well-deserved summer holiday at Solliden Palace on Öland.
