Well not exactly like cutting butter but this WWII bunker got split in two which took 40 days all in the name of art. A diamond wire saw was used to cut through the concrete structure, then a crane came and carried away a middle section, creating a narrow slit.
It took 40 days to slice through the solid concrete bunker, which is one of 700 constructed along the New Dutch Waterline, a series of water based defences used between 1815 and 1940 to protect the cities of Muiden, Utrecht, Vreeswijk and Gorinchem.
