Wells, Somerset
It is the second smallest city in the United Kingdom after St Davids in Wales. The area of Somerset was known in past centuries as a stronghold of taxation avoidance and liquor smuggling (from ships wrecked on the coast). In the 18th century the Bishop of Bath and Wells used to travel with half-a-dozen armed soldiers, and no doubt they were needed. The city has been there since Roman times, indeed it was originally a Roman settlement.
