Photograph of the ramp alongside the west side of the Holland Armory in June 2009. By this time the building was owned and occupied by the Holland Museum.
Massive amounts of water built up outside the building during a very heavy downpour. Within hours there was so much water outside (easily 3 feet) that the exterior metal doors gave way from the pressure. Thousands of gallons of rain and debris then washed into the Armory basement, destroying countless artifacts.
