A concession market
Portuguese casinos operate under regional concessions, which is why they cluster in specific resort zones rather than spreading across the country. Casino Estoril, 18 km from Lisbon, bills itself as the largest in Europe.
Its wartime history is real rather than marketing. Neutral Portugal was full of intelligence operatives, Ian Fleming spent time at Estoril, and the casino is generally credited as the inspiration for Casino Royale.
Our Lisbon guide covers both Estoril and Casino Lisboa in Parque das Nações.
Practicalities
The age is 18 and photo identification is required; Portuguese venues enforce registration properly.
Casino games are taxed at the operator rather than the player, so a recreational win generally arrives whole. Other products have their own treatment and professional gambling is different again.
