Brazil's Banco Central, 2005
It was through a 656-ft.-long (200 m) tunnel that a group of Brazilian burglars infiltrated the Banco Central in 2005. After three months of digging from a nearby farmhouse (during which time neighbors innocently noticed vanloads of material being hauled away daily), the robbers crawled beneath two city blocks to the bank, where they blasted their way through a final meter of steel-reinforced concrete during the weekend of Aug. 6-7. Bank employees had a rough morning when they returned on Monday to discover the hole and the empty vaults, from which nearly $65 million was stolen — especially considering that the money was not insured. Two months after the robbery, the body of one of the crime's suspected masterminds was found on the side of an isolated road 200 miles (322 km) west of Rio de Janeiro.
