Timgad was a Roman city from the first century AD. It was probably a military camp for the legions guarding the southern border. It was planned for 15000 people but the number of inhabitants increased fast. It was abandoned around 600 AD and was discovered in 1880.
It is a good example of Roman city planning with streets, library, 14 baths, theater, forum, ramparts, layout, and arch of triumph.
Unfortunately the weather was not nice, a drizzle of rain (!) and cold, but I really enjoyed strolling up the main street up to the arch. Going through the arch I found myself talking to young girls.
We had a slight language problem as their English was only a bit better than my French, that does not say much. But we managed to communicate. They were facinated with my blue eyes, they thought blue eyes were so beautiful! I sang “Beautiful, beautiful brown eyes” to them, but I don’t think that made any impressions except giggles.
