Upon Dr Penfold's death in 1870, his son-in-law, Thomas Hyland, assumed control of the business, and began to sell some of the land.

A larger subdivision occurred in the early 1980s, when owners Tooth & Co sold much of the area to the east of Penfold Road, resulting in the survival of only the core of the former winery, including production plants and Grange Cottage.

The tornado cut a narrow, 2 km long path of destruction through the suburbs, tearing limbs off trees and tiles from roofs.

[2] Rosslyn Park is situated approximately 6 km east of the Adelaide city centre.

East of Penfold Road, the area is much steeper in its approach to the Adelaide Hills, and contains some large, striking and very modern architecture.

By far the most notable landmark in Rosslyn Park is the Magill Estate branch of Penfolds Winery.

This site offers cellar door sales, tours and the award-winning Penfolds Magill Estate Restaurant.

Bike lanes also exist most of the way along the Parade into the suburb, whilst the development of a 'bicycle boulevard' on the suburban Beulah Road also promotes bicycle usage in the area.
