Serving Altadena since 1935
The Altadena Historical Society (AHS) was founded in 1935. As a 501(c)3 organization, we gather, preserve, and share print and digital information about the people, places, and events that have shaped the Altadena community.
“Eyes on Altadena” will continue through 2022. Read more.
