The Alton Area Landmarks Association, Inc. was founded in 1970 during an effort to save the old GM&O Railroad Station from demolition. Support was widespread, but the building was razed for the Willliam L. Beatty Federal Building on Belle Street.

AALA is dedicated to educating, promoting, and saving the architectural heritage of the Alton area. AALA sponsors the annual Fall Historic House Tour.

General membership meetings are the third Monday of the month. These meetings are free and open to the public. There is a brief business meeting, refreshments, and a guest speaker. Please note that there are some months where a general meeting is not held.
