Which risk increased for Roman castra (military camps) when constructed on peat soils?

💡 Explanation

When castra were built on peat, consolidation settlement occurred because the soil compressible nature resulted in uneven settling. This caused structural stress within walls. Therefore, increased risk of foundation settlement and wall collapse resulted, rather than fire, disease or ambush which depended more on material composition and surrounding terrain.
