There is a lack of 'classic' type sites such hillforts and oppida, and of villas, towns and other Roman-style settlements. Only a few vici were established. Ceramic use and deposition were scarce in the Iron Age, and not widespread or intensive during the Romano-British period, especially the first few decades after the conquest.

Large amounts of limestone fines co-produced during the processing of crushed limestone may be useful in the sequestration of carbon dioxide (CO2). Accelerated weathering of limestone (AWL) is proposed as a low-tech method to capture and sequester CO2 from fossil fuel-fired power plants and other point sources such as cement manufacturing.
