Two permanent collections that often get overlooked. The Thorne Miniature Rooms, located in the lower level just after entry, feature 68 rooms with impeccable detail and scale. From English Great Halls to California Living Rooms, it is easy to get lost in the intricacies of these unbelievable interiors. The Chicago Stock Exchange is equally as impressive. When the original Stock Exchange was demolished in 1972, sections of elaborate stenciled decorations, molded plaster capitals, and art glass were preserved from the Trading Room. Using these fragments, the Art Institute was able to reconstruct the Trading Room in its Rubloff Building between 1976 and 1977. Two definite must sees.
