Commissioned in 1921 as a memorial to L.A. veterans of World War I, the Los Angeles Memorial Coliseum quickly became one of those city landmarks that it would be hard to imagine L.A. without. Construction broke ground on December 21, 1921, and the stadium opened on May 1, 1923, so I’m guessing this aerial photograph, taken when the shape of the Coliseum had become visible, is from the second half of 1922. The area around it is more developed than I’d have expected. In the upper left corner we can see the Exposition Park Rose Garden, which is still around today.
Here’s a 2021 satellite image of the Coliseum:
Not too surprising that it’s developed around that area. Some of the older houses in that area were built around 1900-1905.
