Hoa Lo Prison at night.

This is the notorious Hanoi Hilton. The main prison for our POWs during the Vietnam war. I'll visit here more tomorrow during the day, and I'll be able to enter it so more on that later.
The light is shining on the top edge of the tall wall. If you look close you can see the broken glass implanted into the mortar to serve as a deterrent for climbing the wall to escape.
This prison was put up by the French in the 1880s to house Viet prisoners. You probably remember the term 'French Indochina.' I won't get into a geography lesson, but the Frenchies colonized this part of the world back in the day. The French set a bad precedent here at this prison.
