Apart from bits of lead and three terrible Roman coins these two were found by my T2 its a fairly small area of a late 4th century building that has long gone ! but lots of Stone & heating system tiles.
A CRISPUS CAESAR AE3 A.D. 317 to 326 Reverse Caesar Nostrorum a Wreath around VOT X Minted in Trier Germany. The other a small 13th century A.D. strap buckle. The Stone from the building would have been used as a quarry by later people.
