A place for conversation around long-term thinking,
We need your help to bring The Interval to life.

A venue that is equal parts library, bar, museum, and cafe, The Interval at Long Now will be a place for discussion and small events exploring long-term thinking. We are building a unique social venue: open to the public, welcoming to members, the kind of place you go for a great conversation.

Update: Brian Eno, one of Long Now’s founding board members, will be designing the ambient sound for the space as well as a custom sound and light installation. Brian recently visited us at the Clock assembly space to gather materials for the piece. We’ll have more details to share about this project as we get closer to opening.

In 02006 the Long Now museum in San Francisco’s Fort Mason Center began modestly, a showcase for prototypes of our long-term projects while the foundation's staff worked upstairs. As we have held more and more events, it has become increasingly integral to our core mission of promoting new conversations around long-term thinking and responsibility.

Each year thousands attend receptions and other small events in our space. And well over a thousand visitors drop in each month during our daytime public hours including students, tourists, and many more who discover us when they visit Fort Mason.

The time has come for us to re-make our space to better serve all these guests. Our vision is to create a compelling venue for conversation that invites visitors to spend time in a place that itself encourages long-term thinking.

We've partnered with the design-build studio “Because We Can,” to create a gathering space that incorporates Long Now’s various artifacts, a towering two-story crowd-curated library, and a state-of-the-art A/V system to support a wide variety of live events. We will serve artisan tea and coffee by day, and inspired cocktails by night. This new space will support a wide range of small events and activities for all ages throughout the year.

The result will be a social hub that helps to make long-term thinking more instinctive and common, rather than difficult and rare. It broadens Long Now's outreach to the public and increases opportunities for our members to visit and meet each other. The expanded hours and business will also be a funding source for our ongoing operations.

We have crafted a range of ways to thank everyone who generously supports this campaign at every level. Please note that not all of these benefits will always be available as each are designed and handcrafted for those of you who support us in this early stage.
