Roisia's Cross is a cross located in Royston, Hertfordshire at the cross roads of Ermine Street and the Icknield Way (cum Ashwell Street). Most likeley it was located in the South East angle of the crossroads in the parish of Barkway. This was in the fee of the Lordship of Newsells. The first recorded owner was Eudo Dapifer, seward to William the Conqueror. Whether there was some monument predating this remains a matter for speculation. However the footstone still exists. The eighteenth century antiquarian Reverend William Stukeley described it as follows;
- A flatish stone, of very great bulk, with a square hole or mortaise, in the centre, wherein was let the foot of the upright stone or tenon, which was properly the cross.
