Street believes that the Angel Inn, having been seized by the king, probably then became the property of the Knights Hospitallers. He bases this conclusion on the presence of the arms of the Hospitallers on the East window of Grantham church in 1662 (as recorded by Gervase Holles in "Notes of Arms in Grantham Church", a manuscript held in the British Museum), in place of the arms of the Templars that had been there, indicating that the Templars' property in Grantham had passed to the Hospitallers.
