Constantine is a city in the north-east of Algeria. It is an old city, founded by the Phoenicians. It changed name and rulers (Romans, Numibia, Ottoman empire, French). It is named after emperor Constantine.
The old part of the city is on top of a cliff with a deep ravine down to a river. It did not have much water when we were there.
As a consequence they had to have bridges, seven bridges in different styles.
We crossed a few of them, and one was definitely for pedestrians only as it ended in a lift up to the street. It is the first time I walked over a bridge and straight into a lift.
