Mark Zuckerberg and Priscilla Chan have donated $1 million to the San Mateo County Historical Association to help complete a new rooftop terrace at the San Mateo County History Museum, the association announced last week.
The 2,897-square-foot terrace will be built as the final phase of the museum’s multiyear expansion, extending from the third-floor event space of the new Taube Family Carriage House and Automobile Gallery, museum officials said.
The space is designed to host community gatherings, civic and business events, celebrations and private functions.
The donation brings the association closer to completing its $25.5 million fundraising campaign for the expansion, according to a press release.
The terrace is expected to open in early 2028.
The museum will celebrate the opening of several expansion projects Nov. 7 with a free public event from 10 a.m. to 2 p.m.
The celebration, called History in Motion, will feature the new carriage house and automobile gallery, updated exhibits at the historic Lathrop House and the HERO Natural History Gallery.
