21 Querns Lane, Cirencester, Gloucestershire, Archaeological Evaluation, (OASIS ID: cotswold2-303944)

An archaeological evaluation was undertaken by Cotswold Archaeology in March 2018 at 21 Querns Lane, Cirencester, Gloucestershire. Three trenches were excavated. The evaluation has demonstrated that Roman demolition debris survives at a depth of between 0.65m and 0.74m below present ground level (108.55m AOD and 109.46m AOD respectively) in Trenches 1 and 2. A wall of possible later Roman (2nd to 4th-century AD) date, seemingly representing part of a low-status building or boundary, was identified in Trench 2 at 0.76m below present ground level (109.44m AOD). Evidence of post-Roman, possibly medieval, activity was represented by a robber trench targeting the Roman wall identified in Trench 2. Two deposits observed sealing the identified Roman / post-Roman features / deposits in Trenches 1 and 2 have been interpreted as 'dark earth' or cultivation soils. The recovery of a sherd of mid 16th to 18th-century pottery from one of these deposits suggests that they were subject to at least some element of re-working/disturbance during the post-medieval period. Exclusively modern deposits were identified in Trench 3 to a depth of 1.55m below present ground level (108.55m AOD).

2018年3月，科茨沃尔德考古有限公司（Cotswold Archaeology）于格洛斯特郡赛伦塞斯特市昆斯巷21号开展考古评估工作，共开挖3条探沟。评估结果显示，1号与2号探沟内，罗马时期拆除堆积保存在现今地面以下0.65米至0.74米深度处（对应海拔分别为108.55m AOD与109.46m AOD）。2号探沟内于现今地面以下0.76米深度处（海拔109.44m AOD）发现一处年代为罗马晚期（公元2至4世纪）的墙体，该墙体疑似为低等级建筑或边界设施的组成部分。后罗马时期（大概率为中世纪）的活动痕迹体现为一条盗掘沟，其开挖目标即为2号探沟内发现的上述罗马墙体。1号与2号探沟中，覆盖于已识别的罗马/后罗马时期遗迹与堆积之上的两处堆积层，被解读为“深色土”或耕作土壤。其中一处堆积层出土了16世纪中期至18世纪的陶瓷残片，表明这些堆积层在后中世纪时期至少经历了一定程度的再改造或扰动。3号探沟内于现今地面以下1.55米深度处（海拔108.55m AOD）仅发现近现代堆积。
