Two working piers
Pier 17 was built in 1912 and Pier 15 in 1931. Since April 2013 they have housed the Exploratorium, which holds a 66-year lease from the Port of San Francisco.
The Bay Observatory
The Fisher Bay Observatory, the only new building on the site, holds a gallery on the second floor, reached by an elevator, and a terrace. Both are among the museum’s quieter spaces.
Built to save energy
The museum was awarded LEED Platinum certification in January 2014. Its roof carries 5,874 solar panels, part of its aim to produce as much energy as it uses.
