Celebrating 161 years of Petaluma Masonry
and 300 years of the modern Craft!
Freemasonry is the world’s oldest surviving fraternal organization, and we at Petaluma-Hamilton #180 take great pride in continuing the long tradition of personal improvement, community development, and support for public education that Freemasons have espoused from the very beginning. More than anything we are a group of men of all ages who share the bonds of brotherhood, encouraging and promoting exemplary living and conduct.
On this site you can learn much about our Lodge’s history, many of the associated groups which use our beautiful clocktower building, and even read articles written by our members. Our aim is to help preserve the rich history and values of the Petaluma-Hamilton Lodge in particular as well as bring awareness to the greater impact Freemasonry has had within Sonoma County.
Located at 9 Western Avenue, our historic clocktower has been a cornerstone of Petaluma city living from its erection in 1881. We invite you to join us the first Thursday of every month at 6:30pm for a family meal open to everyone, particularly traveling Brothers and those who have questions about Freemasonry or Petaluma history.
We hope to see you soon!
Worshipful Alex Saslow
