This presentation will address the genesis and multiplication of the so-called ‘Anne Frank Tree’, the horse chestnut tree behind the Secret Annex that Anne Frank wrote about in her diary. Fungus-infected, the tree fell in 2010. The Anne Frank Tree testifies of both the terrible fate of the European Jews and the shelter offered to some. Therefore, its eventual safeguarding, whether by conservation or multiplication, became a topic of concern worldwide. Following the roots and routes of the Anne Frank Tree legacy (stump, seedlings, grafts, wood and chestnuts) I examine the processes of sacralisation that have stirred the material’s vivid proliferation and, importantly, the burden which the accumulating material subsequently imposes on the people in charge of it. Building on David Chidester’s (2018) insights that anything can be sacralised and that scarce resources can develop into sacred surplus, my work on the Anne Frank Tree foregrounds the relation between the sacred, processes of sacralisation and the production of excess. Approaching the processes of sacralisation and proliferation through Ian Hodder’s (2014) notions of ‘entanglement’, ‘entrapment’ and ‘sticky entrapment’, I propose an analytical framework that opens a perspective on people’s dealing with sacred matter that equally brings into view sacred matter’s dealing with people.
