The dig is being carried out by MOLA Headland Infrastructure, on behalf of Highways England.A medieval blacksmiths workshop Discovered during excavations of the deserted medieval village of Houghton, the blacksmiths workshop was described as a firm favourite among archaeologists, offering a glimpse into the daily life of a bustling village community between the 11th and 13th centuries. Archaeological remains have included evidence of metal-working in the form of a pit filled with lumps of slag and hammerscale (the by-product of iron-forging), and post-holes from a wooden building.A wood-lined well Found just west of Brampton, the well is understood to dates to the Saxon period (400 to 1066 AD). The structure is unusually well preserved which archaeologists have attributed to the water-logged Cambridgeshire landscape, allowing them to see how it was carefully constructed to prevent the soft edges from crumbling inward. A spokesman for MOLA Headland, which is carrying out the dig, said: Wells such as this one would have been crucial to ensuring that local populations had access to cleaner water in a watery landscape where contamination would have been a problem.An artificial Roman pond The pond was excavated near Fenstanton and measured around 35metres in diameter. The archaeologists excavated down into the spring and discovered evidence of wooden tanks which would have had some impact on the cleanliness of the water. Archaeologist Elliott McDonald said: Its rare to get such great survival of fragile wood, so it required a lot of care and attention to detail when cleaning it, as well as special wooden and plastic tools to make sure there was no damage to finds.Iron Age cooking pits The pits were discovered close to the village of Brampton and gave the team an insight into domestic life in the period from 700BC-43AD, before the arrival of the Romans. The pits contained charred material and fire-cracked stones which would have been used in cooking. In the Iron Age the stones would have been heated up and thrown into the pits, with their heat slowly being released over several hours.Timber structure Large posts which survived well in the wet ground conditions in Offord Cluny proved to be part of a rare elm-built structure. The posts would have held up the roof of a large-aisled Roman building and have been radio-carbon dated to 120-240AD. According to MOLA, the discover makes the building one only two securely dated elm-built timber structures excavated in the UK.
