Starting with an open bowl-like design and one grandstand with seating, Stamford Bridge had an original capacity of around 100,000, making it the second biggest stadium in England after Crystal Palace. The early 1930s saw the construction of a terrace on the southern part of the ground with a roof that covered around one fifth of the stand. As the roof resembled that of a corrugated iron shed, the stand eventually became known as the "Shed End", although it is unknown who first coined this name. Starting in the 1960s, it became known as the home of Chelsea's most loyal and vocal supporters. In 1939, another small seated stand was added, the North Stand, which remained until its demolition in 1975.
