Roman Earthworks Science

A Fort Science visual pack about how Roman soldiers cut ground, moved spoil, hit hard rock, built turf and earthworks, organised labour and washed the mud off. Built from a corrected evidence dataset with confidence labels on every major claim.

Known Army-built frontier system: ditch, Wall, berm, forts, Vallum and later road.
Modelled One Roman mile of large ditch is about 10,000 man-days under central assumptions.
Do not claim Wheelbarrows, perfect V-ditch everywhere, or fire-setting at Limestone Corner.

Evidence discipline

This page separates known evidence from reconstruction and modelled values. It uses GIS-style BNG plotting for the corridor strip, measured schematic cross-sections for earthworks, and position-on-scale charts for man-day comparisons.

Research status: developing educational synthesis. Keep confidence labels with any public reuse.
