Several contemporary architects have designed architectural objects that are closely linked to their particular sites. An in-depth study of the relevant relationship holding between those objects and their sites is, however, missing. This paper addresses the issue, arguing that those architectural objects are akin to works of site-specific art. In section (1), I introduce the topic of the paper. In section (2), I critically analyse the debate on the categorisation of artworks as site-specific. In section (3), I apply to architecture the lesson learned from the analysis of the art debate.
