Millthorpe is a town located between Orange and Blayney in New South Wales, Australia in the Blayney Shire. At the 2011 census, Millthorpe had a population of 1,109 people. The town was once a major potato growing area and continues to have extensive agricultural activities. The town was originally called Spring Grove.
Millthorpe is a picturesque, compact and historic village set amidst gently rolling hills. Classified by the National Trust, it has a number of fine historic buildings, as well as cobbled, bluestone-bordered streets, art galleries, gift and antiques shops, a museum, two hotels, restaurants and cafes, a bowling club and motel. Two of the main streets, Victoria (which runs east-west) and Park (north-south), follow the contours of the local topography with a more regularised grid system extending outwards from them. Millthorpe is located 252 km north-west of Sydney and 22 km south of Orange.
European settlement of the area began when a government stock station was established in 1823. The town is based upon a land grant originally known as Grove Farm which was made out to convict overseer Charles Booth in 1834. Noted explorer Thomas Mitchell twice stayed there during inland expeditions.
The area developed as a farming centre from 1840 to 1880 with orchards established in the 1860s. Local agriculture received a considerable boost from the arrival of the railway in the 1870s. A large flour mill was established in 1882. Consequently, in 1884 the town's name was changed from Spring Grove to Millthorpe. Today it is still essentially a service centre to the rich farmlands which surround it.
