The economic boom and subsequent collapse (Hrun) of the mid 2000s had a marked effect on Reykjavik, leaving various half-finished and empty structures with uncertain futures. Although the material culture of the economic collapse has been examined to some degree, the abandoned building sites have not. The Icelandic heritage discourse has so far had very little engagement with twentieth-century materiality and even less with twenty-first-century materiality but this paper contends that these places can nevertheless be seen as heritage. In order to engage with such places, the Icelandic authorized heritage discourse must be significantly broadened.
