Where was Facebook's first office in Palo Alto?

Facebook’s first office in Palo Alto was at 471 Emerson Street in Downtown North.

Then still called The Facebook, the company moved here in January 2005 from the house in Los Altos where the early Facebook team lived and worked.

On the wall outside the front door is a sign in the style of Facebook’s familiar thumbs up symbol that reads:

The Face Book
Location of the “First Ever” Facebook Office.
Jan 10, 2005 – July 30, 2006

Leased under the tenant name “The Face Book”
