There's no place in the world quite as famous for its culture as the island kingdom of Great Britain. With over two thousand years of culture from which to draw, the nation and its people celebrate weddings with a uniquely elegant sense of poise and class.

A bride's wedding day is often touted as "the happiest day of her life", but in all honesty it's often a very stressful experience as there are lots of conventions surrounding the whole thing and you can get caught up in family rows, and trying to please everyone, still it's a good test of a couple's courage.

When the guests arrive for a wedding the ushers' duty is to hand out the correct books, flowers and the order of service, and ensure the guests are seated in the correct places. Traditionally, the side on which people sit depends on whether they are friends or family of the bride or of the groom. The front rows are generally reserved for close family or friends, with the very first seats reserved for the bridal party. However, in many ceremonies the bridal party will remain standing at the altar during the ceremony along with the bride and groom.

During the ceremony the bride and groom make their marriage vows. Marriage vows are promises a couple makes to each other during a wedding ceremony. In Western culture, these promises have traditionally included the notions of affection, faithfulness, unconditionality, and permanence.

Most wedding vows are taken from traditional religious ceremonies, but nowadays in the UK many couples choose touching love poems or lyrics from a love song revised as wedding vows and some couples even choose to write their own vows, rather than relying on standard ones spoken by the celebrant.

After the vows have been spoken the couple exchange rings. The wedding ring is placed on the third finger of the left hand, also called the "ring" finger. The wedding ring is usually a plain gold ring. After the wedding ceremony, the bride, groom, officiant, and two witnesses generally go off to a side room to sign the wedding register. Without this the marriage is not legal and a wedding certificate cannot be issued.
