For most couples, the wedding budget decides everything. The dress, the flowers, the music, the guest list. And the catering of course, because that’s most likely to be the biggest talking point amongst all the aunties of the family.
On the other hand, for an elite circle of royals, billionaires, and A-list stars, the budget isn’t a limitation. It’s one massive opportunity to go all out and have the wedding that most people could only dream about. These are the weddings where “splurge” is the starting point, and the final bill could probably buy you a private island.
From London’s grandest cathedrals to the romance of Venice’s canals, we’re giving you a closer look at 12 of the most extravagant weddings in modern history — the people, the gowns, the guest lists, and the staggering price tags that made headlines.

Around 750 million watched on TV across 74 countries, making it one of the most-watched live events in modern day history. At the time it was reported that the wedding costed $48 million, the equivalent of $140 million today. Even adjusted for inflation, it remains the most expensive wedding ever recorded.
