On Wednesday, the Prince and Princess of Wales, both 41, attended the National Service of Thanksgiving and Dedication at St. Giles’ Cathedral in Edinburgh held in honor of King Charles andQueen Camilla’s crowning. The festivities were smaller than theformal coronationin London on May 6 and seemed to have a more relaxed atmosphere. Kate sat next to her husband during the church service, where she smiled, whispered into his ear and even tapped his backside!

Inside St. Giles’ Cathedral, King Charles was presented with the Honours of Scotland, the country’s crown jewels. The suite is comprised of the crown of King James V of Scotland, a sceptre and a new sword of state with aspecial connectiontoQueen Elizabeth. The government of Scotland commissioned a new ceremonial blade named after the late monarch for the National Service of Thanksgiving because the set’s existing sword (over 500 years old!) was deemed too delicate to use.

When the church service concluded, a 21-gun salute was fired from Edinburgh Castle. The Royal Procession traveled back to the Palace of Holyroodhouse, the British monarch’s official residence in Scotland, and the Red Arrows of the Royal Air Force soared overheard for a flypast.

From the presentation of the crown jewels to the processions and pomp, much of the pageantry in Edinburgh for the coronation celebration mirrors the festivities seen at Charles and Camilla’s crowning at Westminster Abbey in May. In early June, the Scottish governmentannouncedthat the King and Queen’s coronation would be commemorated in Edinburgh on July 5.
