Near Jenny Bell's Well is a medieval and post-medieval midden. Two bronze rings were found here in about 1900 and since then it has been partly excavated in the 1980s. The main deposit fills a fault in the bedrock and boulder clay and midden material can be traced for about 200m along the cliff towards Tripping Chare. The midden is about 4m thick at its deepest point and seems to lie on top of a massive drystone structure. Amongst the finds there was 11th to 15th century pottery as well as secular and monastic domestic and industrial debris. Two pieces of Roman pottery from the midden are the only Roman finds from the island.
