the globe, like london's other open-roofed public theatres, employed a thrust-stage, covered by a cloth canopy. a two-storey facade at the rear of the stage hid the tiring house and, through windows near the top of the facade, opportunities for balcony scenes such as the one in "romeo and juliet". doors at the bottom of the facade may have been used for discovery scenes like that at the end of "the tempest". a trap door in the stage itself could be used for stage business, like some of that involving the ghost in "hamlet". this trapdoor area was called "hell", as the canopy above was called "heaven"
