The Interval at Long Now

The Interval at Long Now is a bar, cafe and venue for talks and other gatherings located in historic Fort Mason Center on San Francisco's north shore within site of the Golden Gate Bridge and Alcatraz. The Interval serves delicious beverages in a room full of mechanical wonders and thousands of books.

We are open daily from 10AM to midnight. Events are typically on Tuesday nights a few times a month. Tickets usually go on sale 2 weeks prior to the event. Our talks tend to sell out quickly due to our limited capacity.

Long Now members can purchase tickets before the general public.

The Interval is home to The Long Now Foundation which is dedicated to long-term thinking through projects including building a 10,000-year Clock, the monthly Seminars About Long-term Thinking (SALT), The Rosetta Project, PanLex, and Revive & Restore.
