Dún Aengus

A dun is an ancient or medieval fort. In Ireland and Britain it is mainly a kind of hillfort and also a kind of Atlantic roundhouse.

Etymology

The term comes from Irish ''dún'' or Scottish Gaelic ''dùn'' (meaning "fort"), and is cognate with Old Welsh ''din'' (whence Welsh ''dinas'' "city" comes).

In certain instances, place-names containing ''Dun-'' or similar in Northern England and Southern Scotland, may be derived from a Brittonic cognate of the Welsh form ''din''. In this region, substitution of the Brittonic form by the Gaelic equivalent may have been widespread in toponyms.

The Dacian dava (hill fort) is probably etymologically cognate.

Details

In some areas duns were built on any suitable crag or hillock, particularly south of the Firth of Clyde and the Firth of Forth. There are many duns on the west coast of Ireland and they feature in Irish mythology. For example, the tale of the '' Táin Bó Flidhais'' features Dún Chiortáin and Dún Chaocháin.

Duns seem to have arrived with the Celts in about the 7th century BC. Early duns had near vertical ramparts made of stone and timber. There were two walls, an inner wall and the outside one. Vitrified forts are the remains of duns that have been set on fire and where stones have been partly melted. Use of duns continued in some parts into the Middle Ages.

Duns are similar to brochs, but are smaller and probably would not have been capable of supporting a very tall structure. Good examples of this kind of dun can be found in the Outer Hebrides of Scotland, on artificial islands in small lakes.

Toponymy

The word ''dun'' is, along with like-sounding cognate forms, an element frequently found in Celtic toponymy; especially that of Ireland and Scotland. It can include fortifications of all sizes and kinds:

Scotland

Many settlement and geographical names in Scotland are named with Gaelic ''dun'' ("fort"), as well as cognates in Brittonic languages such as Cumbric and Pictish.

* Drumpellier, Lanarkshire
* Dumbarton, Dunbartonshire
* Dumfries, Dumfriesshire – possibly Brittonic ''din-pres'' ("thicket fort").
* Dundee, Angus
* Dunearn, Nairnshire
* Dunearn, Fife – possibly dùn-Èirinn ("fort of Ireland").
* Dunfermline, Fife
* Duniface, Fife – possibly Pictish equivalent of Welsh ''din-y-faes'' ("fort of the field").

* Dunino, Fife
* Dunipace, Stirlingshire - Brittonic equivalent of Welsh ''din-y-bas'' ("fort of the shallow").
* Dunlop, Ayrshire
* Duns, Berwickshire
* Duntarvie, West Lothian
* Tantallon, East Lothian
* Edinburgh, - Name in Scottish Gaelic is ''Dun Eideann''.

England

Some place-names in England are derived from Brittonic cognates of Welsh ''din'' (c.f. Cornish ''dyn'', Cumbric ''*din''), and fewer perhaps from the Gaelic form. Roman-era toponyms ending in ''-dunum'' may represent an ancient Brittonic ''*duno''.

* Cambodunum, Yorkshire
* Din Guoaroy, Northumberland – obsolete name for Bamburgh. Equivalent to Welsh ''din-gwarae'' ("fort of the play").
* Dinckley, Lancashire
* Dunmallard Hill, Cumberland
* Durham, County Durham - ''Dunelm''
* Glendinning Rigg, Cumberland
* Londesborough, Yorkshire – ''Lugudunum'', from ''*lọ:co-'' + ''duno'' ("shining fort").
* Rigodunum, Lancashire
* Segedunum, Northumberland
* Tintagel, Cornwall
* Uxelodunum, Cumberland – c.f. Welsh ''ucheldin'' ("high fort").

London has been etymologised as Brittonic ''*lin-'' + ''dun-'' ("lake fort"). Coates has rejected such an etymology as "incompatible with early forms".

Wales

* Carmarthen, Carmarthenshire – ''Moridunum'' ("sea fort").
* Denbigh, Denbighshire – from ''dinbych'' ("small fort")
* Tintern, Monmouthshire

Italy

* Duno
* Induno Olona
* Verduno

France and Switzerland

The Proto-Celtic form is ''*Dūno-'', yielding Greek δοῦνον. It is ultimately cognate to English '' town''. The Gaulish term survives in many toponyms in France and Switzerland:
* Autun - ''Augustodūnon'' fort of Augustus
* Lyon – ''Lugudūnon'' " Lugus' fort"
* Nevers – ''Nouiodūnon'' "new fort"
* Olten – ''Ol(l)odūnonm'' "fort on the Olon river"
* Thun – ''Dūnon''
* Verdun – ''Uerodūnon'' "strong fort"
* Yverdon-les-Bains – ''Eburodūnon'' "yew fort"
