A Castle and a Peel?

I was doing some research on castles. Nothing new there 🙂 And I looked up synonyms for “castle”. Well, a lot of the expected stuff was found. You can probably recite a list of them.

The more common ones include fortress, hold, stronghold, tower, palace and manor.  Ok, those are pretty easy.

Then we get to a second level with some that are not as commonly known. I knew them because castles is my thing.  They include an alcazar a safehold, a citadel and a donjon.

Pretty cool and I really love the old fashioned spelling of dungeon. There is writing potential with that word.

But then I ran across one that threw me for a loop. I thought for sure that it didn’t belong in the list of synonyms for castle.  It is the word “peel”. Yup, just like the outside of an orange (noun) or the act of removing the skin from something (verb).

And then , there is a small fortress or fortified tower for residence or for use during an attack. And that is called a peel.

It seems very interesting to me that the word “peel” came to this. I mean what is the derivation of something like this? Does it catch both the noun and the verb versions that we are familiar with? Did a small tower like this have an outer peel of stone and did attackers focus their attention on these outer walls, slowly peeling them away with various siege tools? small-fortress-peel
