Bab Al Madinah Al Munawarrah

This guide to Bab Al Madinah Al Munawarrah in Medina opens with a puzzle: five thousand square meters of curved aluminum and steel rising over the interchange of three highways, built as a gateway with not a single door. It follows the odd relay behind it, from the local firm Dar Al Omran that drew the concept to an Australian fabrication workshop that had already built public sculpture in the kingdom, beginning with a piece called Al Fanar at a coastal university. Every panel of curved metal here was formed by hand and machine, curve by curve, hiding any straight edge or seam.
