Abandoned Silos to Be Converted Into Amazing Inside-and-Out Climbing WallsS

These incredible structures are the results of a contest to determine their best adaptive reuse, won by Amsterdam's own NL Architects. The towers now have climbing surfaces both inside and out as well as multi-purpose areas, offices, restaurants and other commercial spaces. How cool is that?
