This report summarises a central component of research undertaken for a recent master's thesis. The research examines the 17th-19th century Bar Brook lead mills near Baslow, Derbyshire. Using existing survey plans, measured survey, archival research and published sources a clearer insight into function and chronology of the mills materialised. The results demonstrate current scheduling complexity, signifi cant earthworks and structures while highlighting signifi cant survey work by the late L. H. Butcher. The chronology presents a smelt mill (Site 1), followed by a slag mill (Site 2) with a related cupola; a corn mill and pumping station later adopting the area of Site 1, following the slag mill transition downstream. The study recommends that scheduling is clarifi ed and extended to include Site 1, and the work of L. H. Butcher is digitised fully to aid future research. Further research is also recommended to support the chronology and determine the environmental and landscape impacts.
