BEIRUT—The first year of Syria’s uprising, 2011, largely spared Aleppo, the country’s economic engine, largest city, and home of its most prized heritage sites. Fighting engulfed Aleppo in 2012 and has never let up since, making the city a symbol of the civil war’s grinding destruction. Rebels captured the eastern side of the city while the government held the west. The regime dropped conventional munitions and then barrel bombs on the rebels, who fought back with rockets and mortars. In 2012, the historical Ottoman covered souk was destroyed. In 2013, shelling destroyed the storied minaret of the 11th-century Ummayid Mosque. Apartment blocks were reduced to rubble. More than 3 million residents fled, out of a prewar population of 5 million. Today, residents say the city is virtually uninhabitable; most who remain have nowhere else to go.
In terms of sheer devastation, Syria today is worse off than Germany at the end of World War II. Bashar Assad’s regime and the original nationalist opposition are locked in combat with each other and also with a third axis, the powerful jihadist current led by the Islamic State. And yet, even as the fighting continues, a movement is brewing among planners, activists and bureaucrats—some still in Aleppo, others in Damascus, Turkey, and Lebanon—to prepare, right now, for the reconstruction effort that will come whenever peace finally arrives.
