Llanfihangel yn Nhowyn (in the parish of Llanfihangel yn Nhywyn) is situated 1 km from the A5 between the villages of Bryngwran and Caergeiliog, and 15 km in a South Easterly direction from the town of Holyhead. The village lies between two lakes - Llyn Traffwll and Llyn Penrhyn which are both nestled in beds of marren grass. You will pass the Historic site of Llyn Cerrig Bach and R.A.F Valley on the way to the nearest village of Llanfair yn Neubwll .

The History of Llanfihangel yn Nhowyn and its relationship to the rest of Angelsey .

    During the thirteenth century before the conquest of Edward and the fall of Llewelyn  ap Gruffydd (the last prince of Gwynedd )  Môn (Anglesey) was a part of Gwynedd. In 1284 Môn was one of the six shires to be created by Edward and it remained thus until 1974. In 1974 it became part of Gwynedd once more. Due to local re-organisation it has once more become Ynys Môn.

    There existed three hundreds (land divided into a hundred) on Anglesey, and each hundred was divided into two commotes. The word commote is derived from the Welsh word cymydog and means a sense of belonging to a place.

    Historians have disputed that these divisions have come about since early times. Some have suggested straight after Roman occupation. The borders were defined by rivers. The river Llifon was the border between the commotes of Llifon and Malltraeth. The commote of Llifon has been described as a long stretch of sand along the West coast of Anglesey and it inspired a famous couplet by Goronwy Owen (a famous poet)

    Pwy all rif tywod Llifon(Whoever can count the grains of sand in Llifon)        (will defeat the great men of Môn)

    Llanfihangel yn Nhowyn lies in the old commote of Llifon. It is recorded that the parish of Llanfihangel yn Nohowyn had 900 acres in 1821.

    Llanvihangel y Traeth is the earliest record of the village name. Llan + Mihangel (Michael)  means the Church of St Michael on the common by the sea. It is interesting to note that early books comment that if a person were to erect a dwelling on common land before nightfall, and have a fire burning then that person could live in the dwelling rent free!

    The village name has changed over the years and Llanvihangel yn y Traeth and Llan-Fihangel-yn-Nhywyn can be seen in old books. In a postal address book in 1886 we can see the name Llanfihangelynhowyn together with a description of the village with a population of 174. The farms that are mentioned are Dowyn, Penrhyn, Henblas,Ty'n Llan, Glan Gors and Caerellen. Gwyl Mabsant (an old Welsh festival) was celebrated on the 10th of October every year but in latter years it degenerated into nothing more than a fair to employ farm hands. The name that appears on the village signpost at present is Llanfihangel yn Nhowyn and the explanation given is Llan + Mihangel (St Michael's Church) + Tywyn (duneland). Before the building of the R.A.F. base the name given to the dune was Towyn Trewan (Trewan derived from an earlier form of Tref Owain).

Ysgol y Tywyn is situated on the outskirts of the village of Llanfihangel yn Nhowyn in the parish of Llanfair yn Neubwll.

At present there are over a hundred children in the school and the numbers are continually increasing. The majority of children come from the village and the R.A.F. station nearby. Children also travel to school from outside the immediate catchment area.

The school's doors were opened for the first time on the 7th of September 1971. The school was called "Ysgol Babanod y Tywyn" and there were 135 children on the register. Six teachers were employed - including the headteacher Miss M. Annette Williams.
