909 Walnut
909 Walnut (formerly Fidelity National Bank & Trust Building, Federal Office Building and 911 Walnut) is a twin-spire, 35-story, 471-foot (144 m) converted structure in Kansas City that is Missouri's tallest apartment building and 10th-tallest habitable building in Missouri. It is also the tallest residential building in the Midwest outside of Chicago.
In 1997 it was added to the National Register of Historic Places.
The building was built in 1930–31 as the Fidelity National Bank & Trust Building (referred to locally as the Fidelity Building) at an estimated cost of $2,850,000, including bank fixtures. The site had been a two-story post office and federal building until 1904 when Fidelity purchased the site for its headquarters. The two-story building was razed in 1930. The new building mimicked the original federal twin-spire structure, in an Art Deco-Gothic Revival architectural motif.
The building's architect Hoit, Price & Barnes also designed the nearby Kansas City Power and Light Building in the Art Deco style.
