Tufa Construction in Roman and Norman Times

Extract

Perhaps the most interesting feature of the Roman buildings excavated last year at Folkestone is the construction of the early walls of calcareous tufa blocks. These walls underlay later buildings which were erected certainly not later than A. D. 100. The tufa walls then were probably built, not necessarily for Romans but perhaps in Roman style for a British noble, roughly between A. D. 1 and 100.
