Colusa Carnegie Library

The dark gray stone Carnegie at the northwest corner of Jay and Sixth streets faces Courthouse Square and its white brick Courthouse, California's second oldest. Now the Police Department, the Carnegie's library identity is established by its cornerstone and by the names -- Hawthorne, Darwin, Bancroft, Milton, Emerson, Shakespeare -- carved into stone lentils above its first floor windows. It was placed on the National Register of Historic Places in 1990.
