​

The Lake Mills Aztalan Historical Society, Inc. was founded in 1941 and has organized many programs and events over the decades but none have stood the test of time as Aztalan Day has.

​

The Society is a non- profit volunteer based organization and does not receive funds from local, county, state or federal entities, your support during our events such as Aztalan Day, is needed to continue the care of the historic site, museum and collections.
