This splendid Gothic church sits on Sixth Avenue right next to Trinity Cathedral (Anglican/Episcopal) and right across from the Duquesne Club, forming a perfect triangle of old money. The architect was Theophilus P. Chandler, Jr., who also designed Third Presbyterian in Shadyside and the Duncan mausoleum in the Union Dale Cemetery.
An interesting feature of the front is the outdoor pulpit, perfectly positioned for thundering denunciations at the rich robber barons coming out of the Duquesne Club. But that never happens.
