The BodenRaum, also located in the basement / Building C of the Kunsthalle, is accessible directly from Roonstrasse via the loading ramp and through a black metal door – by arrangement with museum staff. The artwork thus has its own address: “Roonstrasse 0.” A mailbox is also located here, allowing visitors to write letters to HHole. Waiting or entering visitors hear the aforementioned composition by French pianist Douglas Guarneri, which he composed specifically for “HHole.”

Entering the space from this door, visitors first pass through a tunnel, illuminated by a black light at the entrance and at the end of which is the burrow. Suddenly, the cry of a newborn child is heard. This is the place where HHole was born. To the left of the burrow, all the drill cores from “HHole” are arranged according to their original location.

A light projector is installed directly under the ceiling, projecting an artificial beam of light vertically upward through all of the artwork’s openings. Photographs and a diagram of “HHole” are presented on both walls, giving visitors an idea of the work as a whole. Due to the darkness in this room, the photographs can only be viewed with the flashlights provided.

Leaving this room and proceeding upstairs to the next levels via the staircase specially designed for the artwork, one can view several photographs from the time of “HHole”‘s creation as they pass by, and smell a scent that changes from level to level.
