Darlington, Western Australia, is a locality in the Shire of Mundaring on the Darling Scarp, bisected by Nyaania Creek and north of the Helena River. Location About one kilometre to the west of Darlington and lower on the Darling Scarp lies the locality of Boya. Between Darlington and Boya there are two abandoned quarries: C. Y. O'Connor's "Fremantle Harbour Works Quarry", now known as "Hudman Road Amphitheatre", and the Mountain Quarry which is also called Boya quarry. They are situated on the southern slope of Greenmount Hill which is defined by the Great Eastern Highway to the north, and the Helena River to the south. The boundary with Glen Forrest to the east has shifted a few times. Geology Darlington is located upon the escarpment of the Darling Fault which trends north-south across the south-west of Western Australia, defining what is known as the Perth Hills. History Darlington developed as a locality from the establishment of the Darlington Winery in the late nineteenth century. Unlike Glen Forrest and Greenmount, Darlington was unplanned. Darlington Hall was originally built for the winery. From 1890 to 1954, Darlington was served by the Mundaring Loop on the Eastern Railway, which bisected the town. Darlington was included in "picnic" and "excursion" train itineraries in the 1930s and 1940s. In 1966, the line was officially closed by act of parliament and the tracks removed. The Railway Reserves Heritage Trail, or "bridle trail" as it is known by locals, now occupies the former railway route, and has become a popular walking and bike trail. Darlington had extensive orchards during the early 20th century. D. H. Lawrence stayed in a local guest house for a short time during his visit to Australia. Guest houses were also used as convalescent homes during the Second World War. By the mid-20th century, many artists had lived in or been associated with the small community. By the late 20th century, the break-up of farms and orchards, with the resulting subdivision of land, had contributed to an increase in the local population.
