T-wall
n.— «Developed by the Israelis in order to put up a physical barrier between themselves and the Palestinians, the Iraq version of these segmented walls is constructed out of thousands of portable, twelve-foot-high slabs of steel-reinforced concrete. When stood upright on their pedestals, these “T-walls” look something like giant tombstones, totems perhaps from some long-lost Easter Island culture gone minimalist. When placed together edge-to-edge as “blast walls,” they form the gray undulations that have now become Baghdad’s most distinguishing feature. And because they proliferated during the administration of L. Paul Bremer III, they became known to some as “Bremer walls.”» —“Baghdad: The Besieged Press” by Orville Schell Mother Jones Mar. 14, 2006. (source: Double-Tongued Dictionary)
