As at 10 August 2007, Collits' Inn and its group of surviving buildings is of national significance for its rare historical, aesthetic, technical and social values. It was built c. 1823 by Pierce Collits and his family and was initially known as the Golden Fleece. It was the first wayside inn built west of the Blue Mountains and was sited to service people and stock using the first roads descending Mount York. Pierce Collits had held various NSW Government positions in the early 1800s and also became a significant early grazier west of the mountains. The inn was well known at the time and operated until Mitchell's construction of Victoria Pass in 1832. The buildings and much of the surrounding property then remained in direct Collits ownership until 1875 as Mount York Farm. The family were later involved in a number of other local inns in the Hartley area. Collits' Inn has an important range of strong historical associations such as those with early Governors of NSW, early surveyors, possible early military connections, a focal point for all roads crossing the mountains for many years and the first country post office. The adjacent cemetery has direct associations with the first settlement west of the Blue Mountains.
