This chapter aims to introduce phenomenal phenomenology as an innovative method of phenomenological interpretation, applying it to interpreting the Langen Foundation Museum designed by Tadao Ando to show how phenomenological concerns dormant within the architectural works can be discovered, revealed and interpreted in a more articulated and comprehensive way. It starts with a critical reading of the way Norberg-Schulz and Frampton have interpreted Ando's architectural works, to highlight what is challenging and problematic for them. Common themes of phenomenological discourse are then introduced as phenomenological concerns. The general structure and characteristics of the proposed phenomenal phenomenology will be explained, concluded by a final section in which this is applied to the case of the Langen Foundation Museum, designed by Tadao Ando.
