Facebook unveiled MPK 21, a new building at its headquarters in Menlo Park, Calif.
MPK 21 was designed by architect Frank Gehry, and the building was completed in less than 18 months.
The new facility features a 3.6-acre rooftop garden with more than 200 trees and a half-mile meandering pathway.
Town Square is a sheltered green space with 40-foot-tall redwood trees. Facebook vice president of global facilities and real estate John Tenanes and Gehry are pictured below in Town Square.
