Marker’s Barn is an outstanding surviving example of a mid-19th century wheelwright’s shop which demonstrates German design characteristics and typical use of local materials, and the typical way of life of the Macclesfield pioneers, the early need for wheelwrights, and the fact that several German "pioneer" settlers also settled in Macclesfield and established businesses here. It also has important associations with the early development and cultural diversity of Macclesfield, one of South Australia’s most significant early rural towns. (2 000 words)
