A Roman settlement was discovered a few years ago during the development of The Forum area of Ingleby Barwick. A Roman Villa is still unexcavated and being preserved under the village green. The rest of the site was excavated just before building houses.
Many thanks to Nat Snell for bringing this one to my attention, below is a slideshow of his pictures of the excavations.
There a lot more detail available on this site on the Tees Archaeology website
