Gregson Park, together with Jefferson Bridge, recently rebuilt in 1993 and which straddles Waterfall Creek, links the bottom end of Waterfall Road and Wyndham Avenue. The small park had its origins in the one of the earliest recorded transactions of the Mount Wilson settlement. The land now known as the property Chimney Cottage was originally sold as Portion 21 to Robert David Fitzgerald, a Civil Engineer from Hunters Hill in Sydney, on 17th June 1875. The original parcel of 9 acres, 1 rood and 12 perches was purchased for twenty six pounds, six shillings and threepence (23/6/3). On 17th September 1920, Robert Fitzgerald signed joint tenancy of this land to his brother Edward, a Newcastle architect. Edward J. Gregson - a dedicated botanist and a lover of the natural bushland - had decided to sell Yengo as his wife Margaret found it too cold and purchase land nearby. The land was sold to Gregson six weeks later on 20th November 1920. On 7th June 1940, Gregson gifted 3 roods of the Chimney Cottage property to His Majesty King George VI; this parcel of land in effect then became Crown Land. Gregson eventually sold this property in 1946. https://www.mtwilson.com.au/gregson-park
