This view of San Francisco reveals a lot about its history. The large domed building in the upper left corner is the Palace of Fine Arts, a pavilion left over from a world's fair the city hosted in 1915. That event was crucial to the city's recovery from the earthquake and fire of 1906 that nearly wiped it off the map.
The cluster of tall buildings to the right of the Palace is the Financial District, As soon as San Francisco become a city due to the Gold Rush of 1849, it became a banking capitol, the "Wall Street of the West." As banking grew through the 20th century, the buildings grew taller. You can see the pointy building known as the Transamerica Pyramid.
The cluster of tall buildings further right went up mostly in the last five years. They represent the explosion of the tech industry in the last twenty years. The tallest of them, and the tallest in the city, is the Salesforce Tower.
Across the middle of the picture, the low buildings with red roofs are part of the Presidio, which was a U. S. Army base from the time of the Civil War until 1994. Before that it was base for the army of Mexico when California was its territory. And before that it was the Spanish El Presidio de San Francisco, established coincidentally in 1776. Now it is a national park.
The railing seen across the bottom of the picture is part of one of the newest structures in the city. It's on a bridge spanning the highway below. A section of that highway has been covered with tunnels. Soon we will be able to walk over them from the Main Post of the Presidio down to the park along the Bay.
So I think it's fair to say, until the bridge was completed last year, no one had ever seen this view of the city.
