These places of magic, mystical megaliths and burial chambers, these places of ancient sorrowful goodbyes and grateful thanksgiving, these places of sacrifice and ceremony, are in abundance here on Anglesey.

The island of Anglesey in North Wales is rich with ancient monuments – over 120 scheduled ancient monuments – that are thousands of years old, and these atmospheric jewels in Anglesey’s crown are well worth a visit. There are, for example, approximately 30 Neolithic / Bronze age burial chambers on the island, several ancient settlements, and Anglesey standing stones are abundant. We are not really aware of their purpose and we have yet to understand many of their secrets, but it is clear they were to do with some kind of pagan / pre-Christian worship. I have read that the strategic location of the Neolithic sites may represent Sagittarius – and that may be the case – but whatever the truth is, they were certainly very important to the people that inhabited our island before us.

Most, but not all, are located within view of Anglesey’s shores. In most cases, the locations are in an elevated position, often within clear view of the Snowdonia mountain range on the mainland. Please ensure that you appreciate how important these sites are, and that care must be taken in order for their successful preservation to continue.

Wherever you travel throughout Anglesey, you are sure to see ancient standing stones, and most would be between 4500 and 5000 years old. The earliest signs of life on Anglesey found during archaeological digs are 8,000 years old, and they are flint workings near Aberffraw.

Without a doubt, this website has the most complete record and photographs of Anglesey’s ancient monuments – and yet I still have so many to do.

Ty Mawr Hut Circles

This site is remarkably well preserved, given that parts of it are 4000 years old. With the remains of about 20 or so round stone houses, stores and workshops, and artefacts like a stone sink deeply embedded in the ground, this site is a must-see. This was

Porthdafarch Hut Circles

The settlement in Porthdafarch on the outskirts of Holyhead is similar to those of Ty Mawr hut circles and thr Plas Meilw settlement. They are all known as Cytiau’r Gwyddelod in Welsh, and that translates as Irishmen’s Huts. This site would be contemporary with her sister sites.

Din Lligwy Ancient Settlement

Located near Llanallgo, the settlement dates from the 4th century AD, where iron was smelted for tools and weapons. Nine buildings still survive on the site, which covers approximately half an acre and is enclosed by a low stone wall. Din Lligwy church built circa 1200AD is

Castell Bryn Gwyn

Located just outside Brynsiencyn. Believed to be an ancient religious sanctuary dating from 4500 BC. I would guess the diameter of the circle to be a couple of hundred feet (ish). When I visit these sites I often wish that the Gwynedd Archaeological Society would have the

Castell Aberlleiniog

Castell Aberlleiniog or Aber Lleiniog was the most difficult to find and access of all the ancient monuments that I have photographed. I will begin by telling you how to get there, but with a word of warning – I have since my visit found out, that

Caer Leb Ancient Settlement

Located off the A4080 Dwyran to Brynsiencyn road, this is easier to find with a Landranger map than to explain it. Caer Leb is a pentagonal enclosure, defended by two banks and ditches, once contained circular and rectangular huts which were occupied in the 3rd century. Each

Ty Mawr Standing Stone

Sometimes referred to as the Trefignath Standing Stone because of its close proximity to the Trefignath burial chambers. I found it easy to access this by parking on the road at the entrance to Holyhead Leisure Centre. Across the road is a field with a sign for

Trearddur Standing Stone

In my opinion one of the easiest to find of Anglesey’s ancient monuments, but pretty unspectacular as a standing stone. Nevertheless as a place to visit it is very worthwhile as it stands just yards from Trearddur Mill and is in a commanding position with nice views,

Pen yr Orsedd Standing Stone 2

Located on the Pen-yr-Orsedd rural farm, just a couple of hundred yards from the main Pen-yr-Orsedd Stone. Not quite as impressive as the main stone, but still over 6 feet tall. Very accessible just through a farm gate and right in front of you. It always amazes
