Humans live in spaces - from the caves of the Stone Age to built architectures and the digital worlds of the present. This always leads to states of being in between. How and where do these manifest themselves in architectural space? How do people deal with the in-between spaces in which they find themselves? And how do artists implement their ideas about this in the image? The authors of this volume deal with various forms of in-between spaces: with the strategies of Nigerian migrants on their way to Europe, with spatial structures in parish churches in southeastern England in the 15th and 16th centuries, or the suburban in works by Camille Pissarro, and much more.
