The Wallberg is the cleared rubble of Pforzheim's destroyed centre, piled up on the southern edge of the inner city and gradually replanted with trees and footpaths. A path winds to a viewing terrace at the top, marked by a memorial cross that names the date of the raid and the dead.
It is a sobering site to walk to from the centre — 20 minutes through reconstructed streets followed by the climb itself. The view back over the city makes plain what was lost and what was rebuilt.
