Where my sister and bro in law stay overlooks a forbidding high walled yard with what looks like a sentry tower in the middle of it. In the Hoi An museum I had seen a painting of the prisoners being freed from the Hoi An prison at the end of the American War and I had thought this was the same place. I asked Hai if there was a prison here and he said there was and he would take me there, so this morning we set off and bypassed what I thought was the prison and headed off down Ly Thuong Kiet, another general who fought the Chinese by the way, and down an alleyway where we passed through the portal of the old prison. I wasn't expecting much as I thought that it would be erased from history, but its still standing. New buildings are going up in the grounds and I found later it's to become a tourist attraction. The blockhouse of concrete with gunports is intact as are the isolation cells. One of the largest buildings is a sort of communal prison. I am guessing it was built by the French, some of the ruined buildings look like they are out of the 1800s. I won;t say too much the pictures can tell the story.
