Citizens of Monaco are forbidden to enter the gaming rooms at the casino.

They check passports at the door to ensure it. The Monte Carlo Casino is extremely famous and located in Monaco. The James Bond film ‘Casino Royale’ was set there. The casino hosted the European Poker Tour grand finals for seven seasons.

The casino is owned mostly by the Monaco government and was opened to keep the House of Grimaldi from bankruptcy. I was there once when I was 16 and got turned away. It was a sad day.
