Longfield Place, Plymouth, Devon. Archaeological Evaluation and Mitigation (OASIS ID: cotswold2-317899)

An archaeological evaluation was undertaken by Cotswold Archaeology in April-July 2014 at Longfield Place, Plymouth, Devon. Nine trenches were excavated, uncovering elements of the former Greenbank Prison, which was constructed on the site in 1849. The evaluation revealed the disturbed remnants of a number of basement cells within the former south-western wing of the prison, part of a panopticon that formed part of the exercise yard and a section of the original prison boundary wall. While there was some suggestion that the line of the Plymouth Civil War defences may ran across the site the earliest artefacts on the site date to between the 14th to mid 18th century. While these artefacts suggest occupation of the site prior to the construction of the prison, no features or deposits of an earlier date were uncovered during the evaluation.

2014年4月至7月，科茨沃尔德考古（Cotswold Archaeology）团队在英国德文郡普利茅斯的朗菲尔德广场（Longfield Place）开展了一次考古评估工作。本次共开挖9条探沟，揭露了1849年建于该遗址的原格林班克监狱（Greenbank Prison）的部分遗存。评估结果显示，监狱原西南翼内多间地下室牢房的扰动残迹、作为操练场组成部分的全景监狱（panopticon）结构片段，以及原监狱边界墙的一段均得以暴露。尽管有线索表明普利茅斯内战防御工事的防线可能横穿该遗址，但遗址内出土的最早人工制品年代可追溯至14世纪至18世纪中期。上述人工制品虽表明监狱建造前该区域已存在人类活动，但本次考古评估并未发现更早年代的考古遗迹与堆积层。
