INSIGHT

Short-Lived Walls Can Have Lasting Trauma

  • The Berlin Wall was short-lived compared with ancient walls but deeply traumatized Berlin's social fabric in just 30 years.

  • Rolf Kabbisch joined a student team that dug narrow, exhausting tunnels under the Berlin Wall using spades and wheelbarrows.
  • They lived in a bakery basement, hid power usage, and moved roughly 200 cubic meters of soil to reach East Berlin.
