Bawn

A bawn is the defensive wall surrounding an Irish tower house.

It is the anglicised version of the Irish word bábhún (sometimes spelt badhún), possibly meaning "cattle-stronghold" or "cattle-enclosure".

The Irish word for "stronghold, enclosure" is dún, whose genitive case is dúin'".

The name then began to be used for the walls that were built around tower houses.
