In an effort to remember and visually preserve my travels, I often like to snap pictures of just about everything, including what I see off the sanctioned path. Wandering through the souq of Marrakech, this road wandered off probably to a residential area of the medina. The fact that it's a little grittier, not made perfect and shiny for tourists and shoppers lends it something of a realism in the midst of the frenzy of souvenirs and haggling it deviates from, if even for a short glimpse to bring me back to reality.
EDIT: On a recent trip back to Marrakech, my friend dragged me along to her new favorite herbs, spices, and cosmetics shop. I was delighted to find that it was just down this road! Dar Al-Atrya sells of course argan oil, but also rose water and oil, spices, all you need for hammam, and more. They didn't pressure us to buy at all when we were there (very refreshing in Marrakech!) and were very helpful. I'll be going back any time I'm back to pick up some more argan or jasmine oil and can't recommend it highly enough. Enter the souq from Djemma el-Fna to the left of the old Cafe Argana (now just a large white sheet) and follow that road for a few minutes until you see these arches. I promise it's not too difficult and is only a few minutes in, near the Fnaque Berbere. Enjoy!
