Treasure Island is for the most part abandoned. The Island started life as a spot for the World’s Fair of 1939. Much of the Island was created on existing muscle shoals located in San Francisco bay. The landfill from the building of the Oakland Bay Bridge was then trucked in and dumped into the shoals. After the 1939 World’s Fair, the city of San Francisco had plans to use it as an airport, but then WWII happened and the island was turned over to the military to use as a base. The base closed down in the 1990’s and has many abandoned buildings.
This is by far the biggest abandonment I have ever seen! Everywhere you look are rows and rows of buildings that are boarded up.
