Bridge of Sighs - The Warden's WifeStop on Haunted Pittsburgh Walk, a free self-guided tour.Now look up. That enclosed stone bridge over Ross Street links the courthouse to the old Allegheny County Jail, and it was named for the Bridge of Sighs in Venice. Prisoners crossed it between their cells and the courtrooms without ever setting foot on the street.The jail's most famous story starts here. In December 1901, brothers Ed and Jack Biddle were sentenced to death. Kate Soffel, the warden's wife, began visiting them, and on January 29, 1902, the brothers escaped with saws and guns she had smuggled in - and she ran away with them. A posse caught up with them two days later in Butler County. Neither brother survived, and Kate served two years in prison. Hollywood retold the tale in the 1984 film Mrs. Soffel, filmed at this very jail.Now the legend. In 1907 a widely printed news story reported prisoners complaining that the Biddle brothers' ghosts were roaming the halls. The jail closed in 1995 and now houses family court, but on an October night you may see why the inmates were nervous.Getting here: Follow the courthouse wall around the corner onto Ross Street, about 2 minutes; the bridge crosses the street overhead.Did you know?: Mrs. Soffel starred Diane Keaton as Kate Soffel, with Mel Gibson and Matthew Modine as the Biddle brothers.Photo op: From the Ross Street sidewalk just south of the bridge, shoot upward so the stone arch frames the street and the jail walls.Stops on this tourFort Pitt Blockhouse - The Last Piece of the FortPortal Bridge - Inside Fort Pitt's WallsBurke Building - The Survivor of 1845Market Square - Where the City BeganAllegheny County Courthouse - The Hill Where an Army FellBridge of Sighs - The Warden's WifeOmni William Penn Hotel - The Grand Hotel's Night ShiftTrinity Cathedral Burial Ground - The Oldest Graves DowntownByham Theater - Opened on Halloween NightFort Duquesne Bridge - The Bridge to NowhereThe Point - Where It All Began
