The north wall of the Jardin Jnan Sbil (botanic gardens) with a quite poignant bit of english-language graffiti.
Actually I can claim the photo is primarily to show the holy nature of walls in Morocco - this dotted appearance is quite common throughout the country.
There's lots of urban myths about why (thoughtfulness for nesting birds being the common one) but apparently the real reason is far more depressing - the nature of the construction is that regular maintenance is required over the life of the wall, so these are holes for scaffolding.
