One such theory is that the name was originally used in reference to Loudoun Hill, being a combination of two Scots words law and dun, which roughly translates as Firehill.

[3] Another Loudoun Hill theory is that the name was originally Lugudunon, which roughly translates as The Fortress of Lugh.

[4] It has also been speculated that the name simply derives from the Celtic word, Loddan, which means marshy ground.

[3] Whilst the origins of Loudoun's name are up for debate, it is known that by 1186 the name was used to describe the surrounding area, as in this year a Royal Charter granted the Lands of Lowdun to James de Lambinus.

According to Blind Harry, Wallace is also said to have fought a battle at Loudoun Hill, during the Scottish Wars of Independence.
