What is it? The ornate, Belle Epoque centrepiece to the pint-sized principality is its main casino, and it’s glitzy even by Monaco standards. Bookable audio tours run each morning but you can’t gamble before 2pm, so best to wait until the afternoon. How else will you win your entry fee back?
Why go? A chance to put on your fanciest outfit, take photos in front of the fountains and Ferraris outside then spend an hour or two sipping fizz, rolling dice or just observing others as if you don’t need the money.
