The Hancock building in Boston has two 300-ton weights on the roof! Find out why they were installe

The John Hancock Building, also referred to as The Hancock, is a 60-story skyscraper in Boston built in 1976. The Hancock held the title of the tallest building in Boston for more than 30 years, as well as being the tallest building in the New England area.

The style for the building was intended to be tall, thin, and show mostly glass as the exterior. Henry N. Cobb took on the challenge to create Boston’s newest skyscraper and landmark. He used the largest windows possible and kept the panes to a minimum. These windows were tinted blue so that the building would blend in with the blue skies on a sunny day. These large windows, lacking the window pane they need to hold, failed and windows started falling from the building on to the sidewalk. This was just one of many repairs made causing the building to open 5 years passed the scheduled date.

After trial and error, and even repairing the building with plywood, the building finally opened. As the building began to become occupied, the building manager was getting complaints from employees that they were getting motion sickness. Most skyscrapers blow in the wind slightly. The movements enable the structure to have some give and take so it doesn’t not have to support all of the wind blowing against it.

In order to make the building sturdier, two 300-ton steel weights filled with lead were placed on either side of the roof. This helped the building from swaying and causing the employees to feel nauseated.
