The Interval at Long Now
The Interval is located in San Francisco within Fort Mason Center, a campus of former military buildings near the Golden Gate. Our building dates to the 01930s and much of it is original to when the room was a forge and machine shop.
Behind the bar you'll see the “ambient painting” created by Brian Eno. Constantly evolving in vibrant colors this generative work of art will go through millions of compositions without repeating.
You'll find many artifacts and prototypes of Long Now's 10,000 year Clock around The Interval, but the two that stand out are the large scale prototypes of the Orrery and Chime Generator. The Orrery is a planetary display featuring all the planets visible from Earth with an unaided eye. The Chime Generator is a mechanical computer for generating a unique bell sequence each day for 10,000 years.
The Interval is home to a unique library: from floor to ceiling thousands of books selected for their value in sustaining or rebuilding civilization. Including great works of literature and references for building infrastructure, making steel, space travel, gardening, math, midwifery, and… come browse our shelves and see for yourself. More about the Manual for Civilization.
Arranged on the ceiling above the bar The Interval’s “bottle keep” features custom-made bottles by Adams & Chittenden Scientific Glass. Both exclusive spirits are made for us by St George Spirits, and are available to our Bottle Club donors whose support has helped us build The Interval. Bottle Club memberships are still available on our 'brickstarter' page.
