Fort Point Arch
The fort beneath the Bridge was obsolete within a few years after its 1861 completion, due to more powerful cannon-fire that could penetrate brick walls 5 feet thick. But the Golden Gate Bridge engineers went to the trouble of spanning over it, rather than demolishing it, using a long-span arch, historic preservation ahead of its time for the 1930s. A suspension bridge works like an arch turned upside down, and vice-versa.
No plans for this exhibit at this time.
