Purdue State Bank

The Purdue State Bank Building is a historic structure in West Lafayette, Indiana, United States, designed by American architect and Frank Lloyd Wright's mentor Louis Sullivan.

Built on a tiny, trapezoidal lot between two streets, the structure is less ornamental than most of the architect's other work, including only a few terra cotta panels.

A local paper at the time referred to Sullivan as "one of the most noted bank architects in the United States".

[3] During the 1950s, a stone portion was added to the back of the building and the original doorway was converted into a window and then an ATM.

[4] The building is located one block from Purdue University and currently houses a branch of Chase bank.
