ARCHITECTURAL GUIDE: MOON, published to broadly coincide with the 50th anniversary of the first manned lunar mission, is a fascinating hybrid of various types of reference guide. From its first pages, the book fully commits to addressing the contradiction contained in its title: namely, how can one discuss the “architecture” of a place that is not just currently uninhabited, but could remain so indefinitely? While other entries in DOM’s Architectural Guide series are organized by region, the Moon guide is, understandably, instead chronological – after all, with most existing structures on the Moon having been built with little to no idea where they would eventually end up, the book can be forgiven for suspending the idea of architecture as a site-specific practice in this case.
