Many people would have trouble pinpointing Lichtenstein on a map. The tiny Alpine principality lies between Austria and Switzerland, and is only 15.5 miles (25 km) long. The capital, Vaduz, has a population of under 6,000.
Sitting in the North Sea between Iceland, Scotland, and Norway, the self-governing Faroe Islands are under Danish rule. The waterside capital is a buzzing place full of shops and highly-regarded restaurants, even though the population was under 14,000 at last count.
With a population of less than 1,500, Saint David's is the smallest city in the UK. Named for the Welsh patron saint, who was born nearby and was buried at a monastery he founded on the site that later became Saint David’s, the settlement was deemed a city due to the fact that it had a cathedral. But it lost its city status in 1888, with the abolition of a 16th-century rule stating that any settlement with a cathedral was automatically a city. Queen Elizabeth II restored the title in 1994, however, and today Saint David’s wears its city status with pride.
