Visitors walk past a bucket of spanners and wrenches as they look inside a warehouse of bankrupt construction firm Alpine in the small town of Trumau, February 10, 2014. Piles of drills, saws, cables, buckets and pumps are being auctioned off to make a few million euros for the creditors of Alpine, a former unit of Spanish construction group FCC. Alpine was a victim of overexpansion in eastern Europe, especially Poland, where a bonanza of road and stadium building for the 2012 European football Championships turned into a legal nightmare that saw firms battling to get paid and dozens of Polish builders go out of business.
