Queen Elizabeth High School, Halifax, Nova Scotia, being demolished, July 2011. Word has it that allotment gardens will replace the rubble for the short term. 

"This effort of thought seems to meet with its greatest resistance in at­tempting to define the thingness of the thing, for what else could be the reason for the failure of the above attempts? The inconspicuous thing with­draws itself from thought in the most stubborn of ways. Or is it rather that this self-refusal of the mere thing, this self-contained refusal to be pushed around belongs precisely to the  nature of the thing? Must not, then, this disconcerting and uncommunicative element in the essence of the thing become intimately familiar to a thinking which tries to think the thing? If so, we should not force our way into the thing's thingness."
—Martin Heidegger, The Origin of the Artwork
