In 1722
William Stukeley visited the site and documented, in his 1724 book
Itinerarium Curiosum, his observations of Roman foundations of walls, floors of houses and regularly-spaced oak posts''. Excavations were conducted by
Nottingham University in the 1920s by
Felix Oswald, and again in the 1960s by
Malcolm Todd. Oswald found prehistoric artefacts including a
Bronze Age flint arrowhead, polished stone axes and bronze socketed
celts. The 20th-century excavations discovered the stone walls and stone slab floors or beaten clay floors of over 20 Roman buildings at the site. Foundations of three large adjacent buildings show that they were the most elaborate at the site. Numerous fragments of window glass, roof tiles and evidence of underfloor heating (floors raised on pillars and box flue tiles) indicate that one of these buildings was a bathhouse. It would have had stone walls, whereas the other buildings were timber-framed with
wattle and daub walls. The largest building had no internal divisions, so it was likely to be a public building. Fragments of decorated wall plaster, mosaic floor tiles, pottery, a grid iron, charred timbers, several wells, water tanks and coins were also discovered. The oldest
Claudian well was lined with oak planks encased in clay, whereas the later wells were stone-lined. The wells drew water from the underground source of the nearby Newton Springs. Oswald identified the route of two other roads crossing the camp. He deduced that one of these was probably used to transport lead from the
Lutudarum lead-mines in
Derbyshire, because a large lead ingot inscribed C.IVL.PROTI.BRIT.LVT.EX.ARG. was found in 1848 at Hexgrave Park near
Mansfield. The site of Margidunum now lies mostly across three fields but it is partially covered by a roundabout built in 1968 == Nearby sites ==
