Dún Aengusa, Inishmore
One of the finest stone forts in Europe boldly stands on the edge of a 100 metre cliff. The fort consists of three concentric semi-circle enclosures surrounded by walls and also has a chevaux-de-frise.
Legend says that the fort delonged to Aengus, a chieftain of the Fir Bolg, banished from the mainland after the Battle of Moytura.

(Baile Locha Riach The town of the Grey Lake)
A Norman settlement was found around a de Burgo manor estabolished after their conquest of the country in 1235. Loughrea evolved into a well-defended medieval town. Today only the town tower and an artificial watercourse, (the only town moat still functioning), are all that remains of the medieval defences.
The ruins of the Carmelite Monastery founded by the de Burgos about 1300 can be seen besides their present church.

East Clare
Killaloe is a name etched in the folklore of Ireland and the great fort of Kincora where Brian Boru resided during his reign as Ireland's High King from 1002 to 1014 covered the site now occupied by the Catholic Church, the village green and a large number of neighbooring houses.
Brian Boru led the cheiftains of Munster and Connaught and their fighting men at the battle of Clontarf where, on the day the great King died, his army defeated the Vikings, ending their domination in Ireland.
At the height of Brian Boru's power Kincora was a masisve fort, its full graneries and copious food stores bursting with natures bounty. The Vikings of Limerick and Dublin were required to pay a tribute of 500 tons of wine a year to Brian's cellars, equal to 100,00 gallons of wine today. During the reign of Brian Boru Kincora was the capital of Ireland but unfortunately nothing but the fame of this great fort remains today.

North Clare and the Burren
Carn Connachtach, Ballydeely
(5 km north-northwest of Ennistymon)
is a striking bronze-age burial mound, 8 m high and about 100 m in diameter.
Frost writing in 189,3 believed the correct name to be Carn Mac Tail, the burial place of Mac Tail, son of Broc, chieftain of Corcomroe and inauguration place of the chieftains of Corcomroe.
Folklore says that the cairn is the burial place of the defeated Connaught army, (hence the name).

The region to the north of Doolin contains numerous cahers or stone ring forts and earth forts (raths) surrounded by ditches.

To the south of the village is an upland area of great interest, scattered with Stone-forts, megalithic tombs and remains of ancient churches.
There is a very high concerntration of habitation, (possibly medieval), to the south of Ballyvaughan, which is interesting since the area was thought, at that time to be outside the extent of Anglo-Norman settlement.

Over the top of Corkscrew Hill is the circular stone fort, which once housed one of Ireland's most famous medieval law schools under the care and management of the O'Davorens, a family of hereditary legal scholars and teachers. Donald O'Davoren is credited as the compiler of both a Breton Law Glossary and "The prophecy of Conn of the Hundred Battles" concerning the succession of the kings of Tara and the coming of St. Patrick.

(Rath Bóirne- Burren earth fort)
(3 km from Cahermacnaghten, in the Feenagh Valley.) There is a medieval church on the site.

(Cathair Baile Cinn Mhargaidh - stone fort of the town at the head of the market)
1.5 km north of Kilfenora is a iron age structure of stone built with double ring walls and a protective belt of upright stones for good defence. Interestingly enough, the fort uses sharp limestone pillars set upright in the ground, a devise known as chevaux de fries, as added defense. This strategy was adopted mainly by tribes of the Iberian Peninsula (Spain and Portugal). Could there have been contact between the two regions in the Iron Age?
