Tetouan houses one of the many palaces of King Mohammed VI. The square located in its vicinity is quite colorful, as can be seen below.
The Tetouan medina is a labyrinth of narrow streets and squares, and filled with all manner of small shops.
What also makes Morocco so fascinating is the people, and the wares and food they sell. The top and 3rd/4th images show characteristic Berber headwear.
Many were not actively involved in commerce. The elderly gentleman in the bottom image, Abraham, is among the last of a once large Jewish population in Tetouan.
