Monument Mausoleum of Mohammed V in Rabat

You're standing at the Mausoleum of Mohammed V in Rabat, right across from the Hassan Tower. Take a look at that white building on its raised platform. It's made of reinforced concrete, but you'd never know it: every surface is clad in white marble. On top sits a green, pyramid-shaped roof. Now look at the colonnades around it. The arches have elegant scalloped edges, and the wall above them is carved with sebka, a classic Moroccan pattern of interlocking diamond shapes.
