Which of the following is the first memorial park established in California?

The first memorial park established in California is Forest Lawn Memorial Park. This cemetery opened in 1906 and was designed to resemble a park rather than a traditional cemetery, featuring beautiful landscaping, gardens, and serene environments that encourage reflection and remembrance. Forest Lawn has set a precedent for the development of memorial parks in the state and has become an iconic reference point for similar facilities across the country. Its innovative design focused on creating a peaceful and uplifting atmosphere for visitors, which is why it is recognized as a pioneering establishment in the realm of memorial parks.

The other locations, while significant in their own right, were established later and might have different characteristics that distinguish them from the original concept of the memorial park as envisioned by Forest Lawn. For instance, Greenwood Memorial Park and Rose Hills Memorial Park are known for their expansive areas and amenities but were developed after Forest Lawn. Hollywood Forever Cemetery, while notable for its historical and cultural significance, does not fit the definition of a memorial park as it primarily serves as a traditional cemetery with enhancements for notable figures and events.
