#1 Charles The Bold & Margaret Of York: $200 Million
To round off this multi-million dollar list is a blast from the past! The 14th-century wedding between Margaret of York and Charles the Bold (duke of Burgundy) was a celebration that historical accounts have described as one of the most stunning and lavish royal weddings in history!
The wedding was a week-long celebration that included feasts, pageants, performances, parades, and jousting competitions! If you calculate the cost of holding such a celebration back in the 15th century, it comes to about $200 million in modern terms – making it arguably the most expensive wedding on this list!
