Wen’s charge is two walls. The interior is twelve feet high, made of reinforced cinder blocks, to support a large geodesic dome; it has doors in each side. The exterior and more recent, constructed in the wake of terrorist attacks, is Quikrete and razor wire. It is taller, and has only a single gate.
Inside these walls, under the dome, is a third wall, or a segment of one: 7.8 meters high, 12.6 meters long, and ancient. Once it held back barbarians. It could be seen from space.
Now, only just, it holds back entropy from its encroach onto glory past.
