1979 photograph shows a Lawrence Livermore National Laboratory employee opening what was thought to be the heaviest hinged door in the world. With a weight of 44 tons, a thickness of 2.5 meters and a width of 3.6 meters. A special bearing on the hinge allowed a single person to open or close the door filled with concrete.

According to Guinness World of Records, the heaviest door in the world is actually the radiation shield door at the National Institute of Fusion Sciences in Japan. It weighs 720 tons, is 11.73 m high, 11.4 m wide and 2 m thick.

The heaviest door in the world, is not designed to keep people out, but to protect the outside world from the contents behind it. Credits to whom it is due.
