Building history
The Cambria Public Library building is a historic Carnegie library. It was built in 1890–1891, with funds provided by the philanthropist Andrew Carnegie. It is one of 3,000 such libraries constructed between 1885 and 1919. Carnegie provided all funds toward the construction and maintenance of the library through 1930. It is a three-story brick building with a tile roof encased in dormers in the French Gothic revival style. It was damaged in the Johnstown flood of 1936 and ceased to function as a library in 1971.

It was added to the National Register of Historic Places in 1972.
