My taste in doors is for the patched and peeling, doors of character. There were even more of these than the studded variety!These 2 examples in Kairouan also demonstrate 3 different knockers to summon different members of the household.
This was a closed up shop in Le Kef
The best examples though were in Tozeur, constrasting with the raised brickwork pattern.
This outer entrance to the courtyard of a mosque was my absolute favourite, a symphony of rusting and patched metal
