An interim report from the 2018 field season of the Aldborough Roman Town Project. Excavation was carried out in the north east corner of the Roman town of Isurium Brigantum between 3 – 27th March 2018 as part of the Aldborough Roman Town Project (University of Cambridge). A 7m x 3m trench was located in order to investigate a large building. First discovered during the 1924 excavations of Barber et al., the extent of the building was fully revealed as part our magnetometer recent survey, showing it to extend to c. 60m x 8m. The excavation was carried out to investigate the nature and date of the building, its chronological relationship to the town wall, and to test whether there was intra-mural road passing immediately to the north of it.

The report contains background to the research, historical maps, geophysical survey from the Aldborough Roman Town Project, and detailed discussion of the results of the 2018 excavations.
