What Is the CMMT?

Welcome to the California Masonic Memorial Temple, one of San Francisco’s most impressive and historic buildings. Opened in 1958, the CMMT is the home of Freemasonry in California. But it’s so much more than that. The CMMT, also known as The Masonic, is also an important venue that has hosted—and continues to host—some of the most exciting and must-see events around. From its striking mid-century aesthetic (designed by the noted Bay Area architect Albert Roller) and its many esoteric references to its uses as both a public venue and the meeting place of the Masons of California, the CMMT is a true San Francisco icon.

The CMMT Today


Since it first opened 64 years ago, the California Masonic Memorial Temple has been an indispensable fixture of the Nob Hill community, hosting both private events for the Masons of California, and also public events for companies and patrons from around the world. 

Most people probably know of the CMMT as the home of the iconic SF Masonic, a 3,300-seat concert and events auditorium managed by Live Nation, which puts on 79 events per year. Over the decades, the venue has hosted countless shows by the likes of Billie Holiday, Tony Bennett, and Van Morrison—as well as comedians like Dave Chappelle, Ali Wong, and Amy Schumer. 


The Annual Communication

One of the biggest yearly highlights at the CMMT is the Annual Communication of the Masons of California. The three-day event is the state fraternity’s annual meeting, which culminates with the election of a new Grand Master of California, the highest-ranking Mason in the state.

There are about 5 million Freemasons worldwide, and approximately 40,000 in California.

A Historic Exhibition Hall


Throughout the years, the CMMT has also played host to numerous business and corporate conferences in its large exhibition hall. Located within walking distance of the many iconic hotels of Nob Hill and Union Square, the CMMT Exhibition Hall was for many years one of the most sought-after spaces in the city, particularly prior to the opening of the Moscone Center downtown.

The Endomosaic Window


One of the true highlights of California Masonic Memorial Temple is the massive, 70-foot-long “endomosaic” window that dominates the main foyer and depicts the history and contributions of California Masons to the state’s history. 

The artwork, created in 1956 by the late Big Sur artist Emile Norman, is neither a typical mosaic nor a stained-glass window. Rather, it is made up of more than 150 hues of crushed glass, plus other materials including soil, plant matter, and metals, all pressed between two large panes of acrylic, or plastic. 

The “endomosaic” is made up of 45 panels divided into three vertical sections. From the central all-seeing eye to depictions of Masonic symbols and historical vignettes, the work is chock-full of esoteric iconography and allusions. To learn more about the artwork, click the link below.

The endomosaic incorporates soil collected from each of California's 300+ local lodges, as well as those of Hawaii, which until 1989 was part of the Grand Lodge of California.

A Labor of Love

The temple was many years in the making. First dreamed up in the immediate aftermath of World War II, it was meant as a memorial to Masons who'd made "the ultimate sacrifice" in the world wars. At the time, the Masonic fraternity was growing rapidly—from about 150,000 members in California in 1946 to almost double that by 1953.

Having outgrown its previous home at 25 Van Ness, the fraternity searched for a suitable location for a new building before settling on the corner of California and Taylor streets, directly across from Grace Cathedral and Huntington Park atop Nob Hill. 

Costing more than $6 million to construct (a sum raised entirely through donations from California Masons), the temple was truly a group effort.

By Masons, For Everyone


The temple’s land purchase and construction costs were funded largely by donations from California Masons. In the early 1950s, members of the fraternity responded to a call to contribute “one day’s labor” to the cause—an average of about $10 per person. In all, the building cost more than $6 million. 

Each member and lodge that contributed to the costs was memorialized in an “open book,” which is still displayed on the second floor of the main lobby.

From the Ground Up


Ground was broken on the temple's construction on Oct. 27, 1955. Nearly three years later, on Sept. 29, 1958, it was formally dedicated before the Annual Communication of the Masons of California. The temple was finally open.

Glitz and Glam


In 1965, the California Masonic Memorial Temple hosted the glamorous San Francisco International Film Festival, drawing Hollywood celebrities and the bright lights.

A Venue for All


Over the many years, the California Masonic Memorial Temple has played host to a wide range of community events, from symphonies to Star Trek conventions. The building also continues to host private and corporate events, and the garage is used by residents and visitors of Nob Hill and Union Square.

For nearly 65 years, the CMMT has been an integral part of San Francisco’s business and entertainment scenes—as it will into the future.
