The Interval at Long Now

The Interval at Long Now, Bar and library in Fort Mason, San Francisco, United States.

Description

The Interval is a hybrid space that combines a library, full-service bar, and event venue inside a converted military building at Fort Mason. The interior merges shelves of books focused on long-term thinking with a working cocktail bar and displays of mechanical clock mechanisms.

History

The Long Now Foundation created this venue by repurposing a military building in Fort Mason into a space for intellectual exchange. The transformation reflected the foundation's mission to encourage extended thinking about humanity's long-term future.

Culture

The space brings together thinkers, writers, and creators who explore humanity's path forward through conversation and shared ideas. Visitors can experience discussions that examine how people might live and thrive across centuries to come.

Practical

Hours of operation change throughout the week, so check ahead before your visit to confirm when the space is open. The location sits in Fort Mason, which is accessible by public transit and offers free parking for those driving.

The library displays working prototypes of a mechanical clock engineered to theoretically function for 10,000 years. The shelves also hold an extensive collection of recordings documenting thousands of human languages from around the world.
