Caer Y Twr Hillfort 

Caer Y Twr also which could be known as Holyhead Hillfort (Use the term Caer Y twr though), is atop Holyhead Mountain in Anglesey/ Ynys Mon, Wales, on the very north western tip of Wales. It sits on Holy Island, a small isle just to the west of Anglesey's mainland, reached by a bridge, but containing the major port for between North Wales and Ireland. The site also has a small Roman watchtower just a under a minute's seconds or so walk or run up the hill, that overlooks the seacape for this important location. 

So here are my slingshot points on this fort. 

* Holyhead port is a major port between Britain and Ireland, along with Fishguard, Stranraer, and Liverpool. Indeed the A5 road, runs all the way from here to London, and the train network heads off to here across the North Wales coast. 

* The fort of course is from the Iron Age, and it is nice to see these good boulders still there, as it is amazing more was not used by builders for the Romans or later societies, I feel, I mean it is so convenient a source fo rocks for the fort. 

* The walls are only needed for a side of the fort, as small cliffs and rock sides, help form a barrier on a side. These are not steep cliffs into the sea, just cliffs on the hillside, like kind of rocky crags, and that kind of thing, and below you just get more moor like hill. 

* You could also call it Holyhead Mountain hillfort, or as of it's Welsh name, Mynydd Tŵr Hillfort. 

* Holyhead nearby has around 10,000 people in it. 

* All I see, is in terms of dating evidence is that this was a Iron Age fort, I do not see much in term of evidence on the web, but it very much looks like one, rather than a Dark Ages one, or even a example that existed in the Roman era. So I think it is fair to say that..

* The hillfort and it's rubble walls, is now covered in grass, heather and such like, and rocks, but is often containing a visitor, or sheep or a bird. 

* The ramparts or walls reach a couple of metres highs at points. 

* It's entranceway is through a rocky gully. The site itself has a entrance way, of ere reasonable width, that is with impressive boulder sizes on either side, as you enter. Typical of forts, to have more impressive higher walls at entrances as they are often weak points for attackers. It has a inturned entrance which lets visitors be seen more clearly by it's inhabitants. 


* So I myself, parked I think east of the fort, and we walked up the path on a swing north then south up the hill to it. From there we saw the Roman watchtower, then walked down into the fort itself to see the pale boulders, and in my opinion decent remnants of walls. 

* About a mile to the west are some fine, Cytiau Tŷ Mawr, Holyhead Mountain Hut Circles, (The background picture of that site, is what is on this page with the picture taken from the wall's of the fort at the top. Some have such as hearths and shelves. Some estimates put these lovely little huts at about 2500 years ago. The info board does anyway. They are just a small walk to the east of the 1821 built South Stack lighthouse, that protected shipping for so long. Now it is a fine tourism spot for visitors, in Summer months. With waves crashing against it even more so in the Winter. 

* It apparently is 6.9 hectares in area.

* From it's top you get a great view of the modern port, and the ferries going west. 

* You can also see across Anglesey,  indeed this hill top can be seen far an wide in Anglesey's mainland. Indeed from higher hills it can be seen further away, such as from Tre'r Ceiri, on the east of the Lleyn peninsula, you can see this summit easily on the horizon, on the relatively flatter rest of Anglesey. I am sure I can see Holyhead Mountain's tip from hills above Colwyn Bay, certainly the Orme on a clear day. It is the highest point in the county of Ynys Mon / Anglesey. 

* Apparently according to http://www.viewfinderpanoramas.org/panoramas/WAL/HOLYHEAD_MOUNTAIN.png you can see Ireland on a clear day. The Wicklow Mountains even, (I did not as it was not that clear) which as of their height, despite being further south, are easier to see than places on a similar precise latitude to Holyhead like Dublin. Though Lambey Isla which is near Dublin is visible on a very clear day. Also the mountains of Mourne much further north are as visible, plus the Isle of Man.   

* The landscape obscures such long views into the rest of Wales, but Great Orme, Anglesey's Bwrdd Artur (and it's hillfort), Penmaenbach, Tal y Fan (It has a small hillfort), Carnedd Llewellyn, Snowdon,  and more can be spotted by expert eyes. With just like Dinas Dinlle, there on a clear day being a good view of the Llyn and it's peaks like Carn Fadryn, Garn Boduan, and Tre'r Ceiri's 25 miles away Yr Eifl.   Bardsey Island at 35 miles away can also be sighted.  

* Holyhead Mountain is 220 metres high. Some may say that is not a mountain, but I think sometimes mountain is a proper geography term, about specific heights, but sometimes it's term just a colloquial term, and from the sea level this looks more of a mountain than a hill. 

* The fact Ireland did trade with Europe and Britain as a whole, as indicated how Irish tombs are  other places have all kinds of beads, or amber from Britain and wider Europe, means you got to wonder how much trade there was between Iron Age Ireland and here, though I can not find it, maybe the trade was sporadic, and erratic, from across adventurous traders, or maybe there were regular routes from ports, like Holyhead, or further away. Surely the roman watch tower indicates there was some level of trade between here and Ireland in there era, that was not just sporadic but had a habit to it.
