Casino Royale : origin

"Royale-les-Eaux, which lies near the mouth of the Somme before the flat
coast-line soars up from the beaches of southern Picardy to the Brittany
cliffs which run on to Le Havre, had experienced much the same fortunes
as Trouville.
Royale (without the 'Eaux') also started as a small fishing village and
its rise to fame as a fashionable watering-place during the Second
Empire was as meteoric as that of Trouville. But as Deauville killed
Trouville, so, after a long period of decline, did Le Touquet kill Royale.
At the turn of the century, when things were going badly for the little
seaside town and when the fashion was to combine pleasure with a 'cure',
a natural spring in the hills behind Royale was discovered to contain
enough diluted sulphur to have a beneficent effect on the liver. Since
all French people suffer from liver complaints, Royale quickly became
'Royale-les-Eaux', and 'Eau Royale', in a torpedo-shaped bottle, grafted
itself demurely on to the tail of the mineral-water lists in hotels and
restaurant cars.
It did not long withstand the powerful combines of Vichy and Perrier and
Vittel. There came a series of lawsuits, a number of people lost a lot
of money and very soon its sale was again entirely local. Royale fell
back on the takings from the French and English families during the
summer, on its fishing-fleet in winter and on the crumbs which fell to
its elegantly dilapidated Casino from the table at Le Touquet.
But there was something splendid about the Negresco baroque of the
Casino Royale, a strong whiff of Victorian elegance and luxury, and in
1950 Royale caught the fancy of a syndicate in Paris which disposed of
large funds belonging to a group of expatriate Vichyites."
