Inishmore means ‘large island’ and this is the largest of the Aran Islands and the one most developed for tourism. It is as its name suggests a fairly large Island, about 12 square miles, and has a year round population of about 900, which increases significantly during the tourist season.

The Forts of Inishmore

The word fort can cause some confusion when used about ancient buildings in Ireland.

In many cases it is quite unclear what the purpose of these places was, but it is certain that they were not forts in to-day’s sense of being an army base. While clearly build to withstand attack, many were family enclosures, built in a time where skirmishes over territory and cattle stealing were common and thus the need to defend obvious.

Others probably had a ceremonial role, though the exact nature of the ceremony is a mystery.

It is certain that although some were later adopted and used by Christian settlements, they pre-date Christianity by some considerable time and are definitely not, as you will ofter read online, early Christian in origin.

Dún Aengus (The Fort of Aengus)

Dún Aengus is the largest of the forts on Inishmore and quite a sight.

Dating back some 3000 years, it’s very large indeed, enclosing an area of some 14 acres and although it looks as though it must have had some defensive use, it is believed it was mainly used for ceremonial purposes.

The fort is built on the edge of a high sheer cliff and consists of concentric horse shoe shaped walls, the inner one 13 feet thick and up to 18 feet high in places.

All the walls were built without morter, you can see where the restored parts are, because morter was used. The walls come right up to the cliff edge, so either the cliffs themselves were considered ample defense on that side or the walls originally there have fallen into the sea at some past time.

The views from the fort are magnificent and worth the fairly arduous climb needed to reach it.

Dún Dúchathair (The Black Fort)

Dún Dúchathair by Neil and Kathy Carey

This again is a walled enclosure built with cliffs on all but one side, making it almost an island in itself.

Some of the walls at Dún Dúchathair are arranged into intricate patterns (see picture above), which again raises the question of whether it was defensive or ceremonial in purpose.

Dún Eochla

This double walled fort, with almost completely intact walls, is situated at the highest point on Inishmore, giving a clear view ofevery part of the island. It is believed to have been built sometime between 550 and 800 BC and was probably home to an extended family and their animals.

Dún Eoghanachta

Unlike the other forts this one is located away from the shore located in western part of the island. Consisting of three low concentric walls it too was probably a family settlement.

What Else to See?

Seven Churches by Neil Carey

Seven Churches by Neil Carey

The monastic settlement known as the Seven Churches (though only two of the buildings were ever used as churches) dates back to the 8th century and there are the remains of some 11th century high crosses here too.

Teampall Bheanain, or the chruch of Bheanain, a saint contemporary with St Patrick, is a tiny church, just 10 sq feet inside, and is claimed locally to be the smallest church in the world.

Clochan na Carraige is a beehive hut and would have been home to a monk.  It has an unusual structure in that although it is circular from the outside the inside space is rectangular.

There is also an interpretive centre and a replica village (very missable). The impression is given that you have to pay to get into the interpretive centre in order to access Dun Aengus, but you don’t, it’s entirely optional.

There are many seals off the shores of Inishmore and the best place to see them is at the Seal Colony, in the north side of the Island about half way along the coast. You see more of them if you time your arrival for low tide.

Becoming a Tourist trap?

Time was when you could just get off the ferry and start to explore the island, walking up to Dún Aengus, and generally enjoying the peaceful and beautiful setting.

The Hard Sell

Now you are met by a crowd of hawkers on arrival, jostling to sell you Island tours in one of the many buses or jaunting cars lined up by the pier. These tours will whisk you around the main sites before depositing you at the interpretive centre.

There you will certainly find some good and interesting information about the Island and the fort, but also yet more touristy souvenirs of dubious quality and another hard sell. There is an “Aran Sweater museum”, which is really a store, full of nonsense about clan aran sweaters, a marketing ploy designed to sell sweaters to tourists.

I can totally understand that the Island people need to capitalise on what they’ve got. I just fear that by over doing it they may spoil what is a near perfect place.

And I’m sad to report that that Supermacs (think McDonalds) have opened a large outlet on Inishmore. Where will it end?

Should you go?

Living dangerously by tbennett

Yes, yes, yes – please go, it’s a wonderful place. Fight your way through the offers of tours and hire a bike to tour by yourself – nothing is more than 3-4 miles away from Kilronan where the ferry lands and is a very pleasant cycle. Or walk.

Do not head straight away for Dún Aengus – as most will – but for the equally interesting but far less visited Dún Dúchathair or either of the two other forts.

The cliffs near Dun Aengus are easily the match of those at the Cliffs of Moher, and you can just walk along them unimpeded by ‘interpretive centres’ (I still don’t understand why cliffs need any interpretation) or obstacles. You can, if you dare, even sit on the edge, dangling your feet over the wild Atlantic.

Just be really careful!

    My mother and I went to Inishmore yesterday for a day trip and loved it. We did not find it to be overly touristy or a major tourist trap, and we were there at high season. Yes, there are people trying to sell you an island tour or a horse cart ride, but this was a few guys asking if we wanted a tour and that was pretty much it. I’ve traveled in a lot of places where you literally had to push your way through big crowds of yelling hawkers, and didn’t consider this a hard sell at all; in fact it was a refreshing change from the more highly populated tourist destinations. The Supermacs is one fairly small place, not a large outlet. The Aran Sweater store has a large selection of really beautiful clothing. Are they trying to sell their goods to tourists? Of course they are. Is the island in danger of becoming a tourist trap? It doesn’t look like it to me. The heading (above) ‘Should you go?’ really surprised me, and I hope readers who have not yet been to this charming and lovely island won’t be biased before they go.
    We had a really lovely walk on the island, from the sheer and dramatic cliffs near Black Fort to the seal colony on the north shore, which didn’t have any seals but was still beautiful. I would like to find out when the seals are most likely to be present during which times of the year.
    Of course, everyone is entitled to their opinion, and mine is that Inishmore Island is a delightful place to visit, fairly simple without a lot of frills, with some commercial enterprises aimed at tourists, but you can take these or leave them as you wish.
    Yes, please do visit the Aran Islands!

      Hi Meredith,

      I am really glad you loved Inishmore, it is such a lovely place. I don’t think I was trying to put anyone off going, if it comes across like that then I didn’t mean it too.

      I think the thing that struck me when I visited again after a fairly long interval was how much more developed it had become and how much harder the sell to tourists was. I felt a point had been reached beyond which there was a danger of spoiling what was there. I am glad that seems, from your experience, not to have happened.

      The thing that annoys me is not selling to tourists – which of course isn’t a bad thing at all, for either customer or store – it’s lying to people in order to sell. A reasonable amount of this goes on everywhere – sanitizing of history etc – but the whole clan Aran sweater thing is such an absolute invention with no meaning or history or heritage WHATSOEVER attached to it.

      Both on their website and in their sales spiel, they perpetuate a false history of the aran sweater that is totally untrue and that they absolutely KNOW to be untrue. It’s really cynical: “Sure we can spin any old yarn to those Yanks, they’ll lap it up the poor ejits.”

      I don’t care how effective a sales tactic this is, or how cutesy it is, they are selling by propagating nonsense and lies and it really does make make me see red.
