Defining what a city is, is a wee bit more complex than measuring its length. But to answer your question, the worlds smallest city that has record of its size is Hum, Croatia and its only a little more than 4 sq km so it reasonably could be as little as 1/4 mile long, and it has a population of 20 as of the 2011 census.

They already make ships that are as big as cities, have you ever stood next to a large cruise ship? They're way bigger than you think, larger than freight ships and air craft carriers, and they can house thousands of people.

The largest cruise ship in the world is a cruise ship called Wonder of the Seas, it's *1,187.8 feet long (that's almost 1/4 mile) and can carry up to 6,988 passengers.
