Where is this building that delivers historical beauty?
Inspired by mid-18th Century Parisian architecture, this historical gem of a building experienced an early 21st century re-birth. Also marked by a post-great Chicago fire of 1871 paranoia, the structure is framed entirely in cast iron down to the doorjambs and window frames. Its decorative details and forward thinking use of light alone merit a visit. Can you sort out this week’s location and post an answer?
