William and Kate on their wedding day
The pair became engaged in 2010, and their wedding instantly became the biggest national event since the nuptials of William's parents, Charles and Diana, in 1981. As soon as the engagement ring (14 solitaire diamonds surrounding a 12-carat oval blue Ceylon sapphire set in 18-karat white gold, originally belonging to Diana) was on Kate's finger, speculation was rife about everything from the venue to the honeymoon destination. The couple eventually chose a Westminster ceremony followed by a reception at Buckingham Palace, with a staggering 1900 guests in attendance.
The day was a lavish celebration, which combined formal traditions with personal touches and gestures from the couple's close friends and family. Prince Harry was the obvious choice as William's best man, whilst Kate's sister Pippa took centre stage as maid of honour. Kate, in a stunning white lace Sarah Burton gown accessorised with a now-iconic halo tiara, which was designed by Cartier and borrowed from the Queen herself, changed the face of bridal fashion forever - and William scrubbed up rather well in his officer's tunic, too.
From the opening notes of the ceremony, to the closing fireworks display, every detail was documented, and had been carefully chosen for a reason. Even the wedding cakes had special meaning to the couple, with one eight tier floral cake made by designer Fiona Cairns standing proudly next to a McVities chocolate biscuit cake - a favourite of William's, which he specially requested for the day.
