In 1515 June 30, Sir Peter Eggecombe (Sir Piers Edgecumbe; Sir Peter Edgecombe) was granted, by Henry VIII, (In year 7 of his reign) a Royal licence to crenellate Estonehouse (Stonehouse Town Defences)

"Licence to impark lands in Westonehouse and Cremele, Devon, and Cuthele, Cornw., and to inclose and fortify his manor of Estonehouse, Devon"

Granted at Westminster, by s.b..

It is somewhat unclear if this licence was to build fortifications for the manor (ie an urban defence) or for the manor house.

(In fact, the original source given is usually a transcription/translation of what are precious medieval documents not readily availably. It should be noted that these transcription/translations often date to the nineteenth or early twentieth centuries and that unwitting bias of transcribers may affect the translation. Care should also be taken to avoid giving modern meaning to the medieval use of certain stock words and terms.)
