This morning the episode of Great Railway Journeys that was shown was the one where Alexei Sayle travels from Aleppo to Aqaba. In his opening remarks, when he showed a map, he mentioned Krak des Chevaliers and, as it's a very impressive place, I waited for that section keenly. It came and went so briefly that I almost missed it, being barely mentioned in passing. So I thought that I would redress the balance.
For anyone who doesn't know, Krak des Chevaliers is a crusader fortress in Syria. I visited it and slept in the grounds when I was travelling around Northern Africa in 2001. Here a few representative pictures. Sorry that the scans aren't great. My scanner is on its last legs.
