THEME: Hadrian’s Wall
The Wall’s construction methods were relatively simple; the most complex part was likely logistics, which can only be inferred. Supplying sufficient quantities of necessary materials – stone, mortar, timber, turf, and metals for construction; food, fuel, and water for builders and pack animals – across the width of Britain without robust transport infrastructure was an immense challenge. A huge amount of wood was required for scaffolding, cranes, limeburning, and buildings, and it probably severely deforested the local environment. Indeed, provisioning the straight timber required for the scaffolding alone could have been a logistical bottleneck in the overall project.
Before construction began, the line had to be surveyed by the ten (surveyors) of each legion, using the to set out alignments and measuring intervals for positioning milecastles and turrets. The line was probably surveyed beginning from east and west toward the centre by two teams working simultaneously, which could have taken two to three months. After surveying, construction began on turrets and milecastles, simultaneously with
