At 5000 North Marine Drive is The Aquitania, a co-op building constructed in 1923 and listed on the National Register of Historic Places since 2002. The Aquitania was built by Ralph C. Harris and Byron H. Jillson in the Classical Revival style. It was developed by George K. Spoor, the co-founder of Essanay Studios, a producer of silent movies in the first decades of the twentieth century. At this time, Chicago rivaled both New York City and Hollywood in film production, and Spoor was able to use his considerable wealth to build an apartment he felt fitting for the film stars connected with Chicago's growing entertainment industry.
