This is a list of the buildings, in England and Wales, known or suggested to have been granted a licence to crenellate. There are also included some other documents that have been proposed as licences to crenellate, but which can be rejected as such. Also in the list are a few houses licenced to be fortified but specifically without crenellations.

It should be noted that the original sources of this information is handwritten medieval latin, often writing in a small hand with many abbreviations, and that different authors have transcribed some of the words, particularly place names, differently. Alternative transcriptions are given in [square brackets]. Information not given in the primary source (or calendar) but derived from context or other sources is in {curly brackets}.
