A photographer captured these surreal photos of North Korea's capital on a state-sanctioned tour

The Trump administration is weighing new legislation that would ban US citizens from traveling to North Korea, following the death of American student Otto Warmbier.

Despite warnings from the US Department of State over the years that visitors stepping into the DPRK risk arrest and long-term detention, approximately 100,000 people - including some Americans - visit the hermit kingdom annually. Tourists may travel independently or go through a state-sanctioned travel agency. They are supervised from the moment they arrive.

In 2016, photographer Raphael Olivier booked an architecture-themed tour of Pyongyang, the capital of North Korea, and captured these remarkable images.
