Excavations at Billingborough between 1975 and 1978 revealed a Middle Bronze Age enclosure and extensive Late Bronze and Early Iron Age salt-making debris. This forms the report on findings from the site, outlining the excavation itself and the finds: Copper alloy objects, iron, flint, terracottas, worked bone and antler, skeletal remains and an important pottery sequence for this region. The final discussion sketches a history of the different phases of the site from the 2nd millennium BC to the 1st century AD.
