[6] The Ashby family instigated the building of a Friends meeting house in 1912 which served as a venue for several religious denominations, the local dramatic society and other community events.

It has had a significant impact on the local community through service projects such as cleaning up the land by Eden Hills Station, fundraising for the droughts and teaching youth to be global citizens.

Watiparinga Reserve and adjacent land near Gloucester Avenue in Eden Hills was added to the Register of the National Estate in 1996.

It comprises approximately 32 hectares (79 acres) and is considered a significant cultural landscape, exhibiting a diverse range of flora and provides an early example of nature conservation efforts in South Australia from the 1950s.

During World War II, the former railway tunnel in the reserve was used for safe storage of South Australian art treasures and is now used to grow mushrooms commercially.

Colebrook Reconciliation Park in Eden Hills was established from 1998 as a memorial to the children who were removed from their families and housed at Colebrook Home, a "United Aborigines" mission which had originated in Oodnadatta in 1924, moved to Quorn, then finally relocated to Eden Hills in 1942.

[16] At its Eden Hills location, Colebrook Home continued to house children, including prominent Aboriginal Australian health worker and public administrator Lowitja O'Donoghue.

This led to memorial works including Fountain of Tears, created in 1998 by Silvio Apponyi and Grieving Mother in 1999.
