It is widely held that the Angel Inn was once a "commandery of the Knights Templar" (as reported in both White's 1846 "History, gazetteer, and directory of Leicestershire" and Allen's 1834 "History of the county of Lincoln"). However, the Reverend B. Street, curate of Grantham, stated in 1857 after his own investigations that "such is not the case". "I have read a document drawn up at Grantham, October 15, 1291," he wrote, "which certainly refers to the property, as belonging to the Knights Templars, but not as being a Preceptory of the Order.".
