Not even buillt fpr skating. just some structure in Montreal. They were gonna tear it down and a bunch of skaters petitioned for it to remain and the spot was granted the title of national monument and cant be destroyed. There's also a book about it called Pipe Fiends. I aint been there in ages but it pretty gnarly to skate. The kinda spot that pretty much only the locals who've been skating it for years can really get loose with
