Letocetum is the remains of a Roman settlement. It was an important military staging post and posting station near the junction of Watling Street, the Roman military road to North Wales, and Icknield (or Ryknild) Street (now the A38). The site is now within the parish of Wall, Staffordshire, England. It is owned and run by the National Trust, under the name Letocetum Roman Baths Site & Museum.
