The doors in Sidi Bou Said are often stunning. They were normally big and grand, typically painted in blue (no surprise here) and decorated with black studs. These beautiful blue doors have become synonymous with Tunisia and are featured in many postcards. What I found interesting about these doors was the door-within-a-door concept. It's totally amusing to me that they would go to the lengths of building such a big and heavy door only to have a smaller door within it for easier access.
