Arch Rock (Topanga)

Arch Rock was a natural arch formation located just south of Topanga Canyon[1] along the coast of Santa Monica Bay, Los Angeles County, California in the United States.

[2] It was a popular destination for day trips from the young town of Santa Monica.

[3] The arch collapsed or was surreptitiously demolished the evening of March 24, 1906, possibly because it was an inconvenient obstacle to creating a coast route for the new-fangled automobiles.

[2] A coach route had previously traveled right under the arch but was only accessible at low tide.

[5] Nearby Castle Rock was demolished as part of a road expansion project in 1945.
