The Arch of Reunification was in which country?

This is the most isolated country in the world. They build meaningless structures like this while millions of their people starve.

Player #109668975, "Meaningless structures" yes: but what about the money they waste on the president's palace and excesses, and military expenses, including nuclear missiles. I don't need to worry about offending North Koreans, they don't have access to free internet.
