In San Francisco builders are required to provide public space when they build new commercial buildings. As a result there is a lot of public spaces in the form of rooftop gardens and courtyards where general public can visit. Many of these spaces are hidden. I just discover some of them after joining a 2-hour tour offered by San Francisco Citywalk. Let's first look at the rooftop garden at Wells Fargo which can be access from Crocker Galleria -- a shopping mall/food court where I visit once in a while. I know where to have lunch next time. . . .
Access the garden from the top floor of Crocker Galleria.
On the other side of the garden is the 1914 Hobart Building.
And across Market Street is the Palace Hotel.
