Recently I was able to tour a museum that was originally a mansion from the Golden Age. All my doors today are from the Driehaus Museum, 40 E Erie St, Chicago, IL. The grand front entrance gives a clue of what is inside.
The first door after the entrance doors is extremely elaborate and my photo does not do it justice. Many of the interior doors are pocket doors that appear to be intact and just not visible. The doorway that the pocket door is in is almost two feet wide.
Many of the doors that would have closed rooms off have been removed. Because this is no longer a family home and the rooms need to be open to allow visitors to travel through easily. The main floor is very much furnished as it would have been at the time, the next two floors have minimal items in them but are still quite beautiful.
The final door is very much a modern door for access and looks as if it replaces a door that would have been used by the household help but certainly does not detract from the exterior.
