Report on the excavation of three trial trenches, dug to inform proposed development on land to the east of Spring Farm, Great Carlton. The trenches were located to investigate features identified by a previously conducted earthwork survey, thought to represent medieval building platforms. The trenching resolved the platforms as being of natural origin, created by the erosion of hollow ways on the site. The remains of four silted up ditches were revealed underneath one of the platforms, however, and a range of 16th and 17th century material was recovered from their fills. The ditches could be seen to drain into the hollow ways and are thus very likely to relate to water management in this area during the early post-medieval period.
