Description

The concept of “adit” represents a horizontal passage that provides entry into an underground space. It expresses a structural form designed for access rather than descent. This identity reflects the meeting point between surface and subterranean environments. As an abstract notion, an adit symbolizes transition into hidden or interior spaces. It marks a boundary where open terrain shifts into enclosed pathways. In this sense, “adit” captures the essence of horizontal underground entry.
