<P> The Globe's actual dimensions are unknown, but its shape and size can be approximated from scholarly inquiry over the last two centuries . The evidence suggests that it was a three - storey, open - air amphitheatre approximately 100 feet (30 m) in diameter that could house up to 3,000 spectators . The Globe is shown as round on Wenceslas Hollar's sketch of the building, later incorporated into his etched Long View of London from Bankside in 1647 . However, in 1988--89, the uncovering of a small part of the Globe's foundation suggested that it was a polygon of 20 sides . </P> <P> At the base of the stage, there was an area called the pit, (or, harking back to the old inn - yards, yard) where, for a penny, people (the "groundlings") would stand on the rush - strewn earthen floor to watch the performance . During the excavation of the Globe in 1989 a layer of nutshells was found, pressed into the dirt flooring so as to form a new surface layer . Vertically around the yard were three levels of stadium - style seats, which were more expensive than standing room . A rectangular stage platform, also known as an apron stage, thrust out into the middle of the open - air yard . The stage measured approximately 43 feet (13.1 m) in width, 27 feet (8.2 m) in depth and was raised about 5 feet (1.5 m) off the ground . On this stage, there was a trap door for use by performers to enter from the "cellarage" area beneath the stage . </P> <P> The back wall of the stage had two or three doors on the main level, with a curtained inner stage in the centre (although not all scholars agree about the existence of this supposed "inner below"), and a balcony above it . The doors entered into the "tiring house" (backstage area) where the actors dressed and awaited their entrances . The floors above may have been used as storage for costumes and props and management offices . The balcony housed the musicians and could also be used for scenes requiring an upper space, such as the balcony scene in Romeo and Juliet . Rush matting covered the stage, although this may only have been used if the setting of the play demanded it . </P> <P> Large columns on either side of the stage supported a roof over the rear portion of the stage . The ceiling under this roof was called the "heavens," and was painted with clouds and the sky . A trap door in the heavens enabled performers to descend using some form of rope and harness . The stage was set in the south - east corner of the building, so as to be in shade during afternoon performances in Summer . </P>
