The Rookery staircase in Chicago was built in the 19th century during an age of opulence when people wanted to show off their wealth. The building itself is a mixture of many architectural styles, but it's most noted for its extravagant ironwork and how ornate each floor becomes as you go up higher.
The Rookery stair case located at one hundred west Monroe street that leads into the lobby with artwork on display (Kaminski). It has been said by historians about this place "It's almost like walking through your grandfather’s house" which makes sense because they were designed using classic Victorian ornamentation techniques.
