Saint David's, Wales
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.
