'Place

Hackers' are part of a new global movement with active groups from the

UK to Australia and the US. These urban explorers find adventure,

adrenaline and often danger in places that most people would not dare to

enter, and involves sneaking into former military bases, underground

cities, decommissioned hospitals and power stations and even the odd

skyscraper – while it’s still being built. 'The idea behind urban

exploration is revealing what’s hidden in the world.” says Bradley

Garrett and Oxford University academic and place hacker. 'It’s about

going into places that are essentially off-limits and, because they are

off limits, have been relatively forgotten. The goal of the urban

explorer is not just to explore these places but also to photograph them

and share these with others so they can see what they’re like.' Place

hackers, like nature explorers, tend to value a low-impact credo: no

vandalism or theft, take only photographs, leave only footprints. (Bradley Garrett/eyevine/zReportage.com via ZUMA Press)
