Andreas Duscha presents precise, comparative photographs of interfaith prayer rooms in airports—spaces situated between transit, security architecture, and quiet devotion.

Since the late 1980s these neutrally designed rooms have proliferated worldwide in response to mobility and migration. The book examines their signage, materials, and codes, asking how and where local religious traditions surface within standardized settings. A cultural-historical perspective situates the series and shows how a “minimum sacred” is negotiated within secular infrastructure.
