Traditional mortars in North-East Yorkshire: Part 1 – Historical context and early mortar practice

The first part of this two-part paper establishes the historical, geological and craft-based foundations necessary for understanding the development of traditional mortars in Bransdale and the wider North York Moors region. Drawing on archival evidence, landscape history and long-standing building traditions, the paper situates mortar use within a distinctive cultural and geological environment shaped by local sandstone, oolitic limestone sources, historic farming patterns and vernacular construction practices. The paper outlines the characteristic forms of pre-modern masonry, including earth-lime bedding mortars, lime-rich pointing mortars and regionally specific plastering traditions. Key technical terminology, lime preparation methods and material characteristics are introduced to contextualise later analytical work. Two representative case studies — Moor Houses Farm and Low Lidmoor Farm — illustrate the continuity of techniques and materials over several centuries and underscore the significance of local craft knowledge. Together, these strands provide a comprehensive backdrop to the analytical results presented in Part 2 and demonstrate the coherence of Bransdale mortars within broader regional traditions. This paper represents a summary only.1 The analysis for this paper was carried out by Bill Revie, whose technical input has been fundamental to the work presented here.
