Liechtenstein is renowned for its Alpine scenery and historic castles, but the tiny principality also punches above its weight when it comes to a more down-to-earth tourist attraction – namely casinos.

Six currently operate there, dotted across a microstate a tenth the size of London and with a population of just 40,000, earning it the nickname “Las Vegas of the Alps” among punters.

All have opened since 2017, after a change in the law made gambling legal, welcoming crowds from Germany and neighbouring Switzerland and Austria to try their luck on slot machines and at tables offering roulette and poker.

But all will have to close if supporters of a casino ban being put to a referendum on Jan. 29 get their way.
