Architect Jens J. Jensen—not to be confused with landscape architect Jens Jensen—designed this 1925 structure. The sprawling, double courtyard brick apartment building looks like a castle, with crenelations, turrets and towers. A moat-like pond was once graced by live swans. This feature has been removed, but the bridges and some retaining walls remain. Inside the complex, an extravagant indoor pool, reflecting the opulence of the era, remains one of Chicago's best-kept secrets.
