1 Best Sight in The Thames Valley, England

Swan-Upping

This traditional event, which dates back 800 years, takes place in Marlow during the third week of July. By bizarre ancient laws, King Charles owns every single one of the country's swans (just as his mother did before him), so each year swan-markers in skiffs start from Sunbury-on-Thames, catching the new cygnets and marking their beaks to establish ownership. The King's Swan Marker, dressed in scarlet livery, presides over this colorful ceremony.
