Etymology

'The Roman station', v. cæster , ceaster . The prefix Thwang - etc. is clearly from þwang 'a thong' in some transferred topographical sense, though it is not clear what this is. Caistor has been identified with Bannovalum 17 (13) Ravenna 24a. Rivet and Smith RB 265b suggest either Caistor or Horncastle, and it seems more likely that it should be identified with Horncastle.
