Located on Philadelphia's historic Main Line, Chanticleer retains a domestic scale and welcomes visitors for relaxation, walking, and picnics.

[5] Upon inheriting the estate in 1946, their son, Adolph G. Rosengarten Jr. established a foundation to ensure that Chanticleer would be developed as a public garden.

Rosengarten Jr. hired Christopher Woods, a native of Britain, to develop the garden.

After Rosengarten Jr.'s death in 1990, Woods became the founding Executive Director and began a radical revision of the garden.
