Menai Bridge (Welsh: Porthaethwy; usually referred to colloquially as Y Borth) is a town and community on the Isle of Anglesey in north-west Wales.

At the eastern edge of the town is Cwm Cadnant Dingle which is now by-passed by a modern bridge constructed in the 1970s.

In December 2015, heavy rains caused flooding which washed away rare plants representing twenty years of work by Anthony Tavernor.

[8] The palace was demolished in the early 1960s and replaced by a block of flats, Glyn Garth Court, completed in 1966.

When the bridge opened in 1826, the ferry closed, but connections with the sea remained through the import, export and shipbuilding trades.

From 1877 to 1920, the ship HMS Clio was docked at Menai Bridge; it was lent to the North Wales Society to teach young men the ways of seafaring.

[9] The young men on the Clio were not permitted to leave the ship; some of the corporal punishment administered was cruel.

Stories about life on the Clio were commonplace among the residents of Menai Bridge; for many years, some mothers threatened their misbehaving children with being sent to live on the ship.

[citation needed] Carreg yr Halen is a small tidal island in the Menai Strait.

[10] Its centre lies approximately 20 metres offshore from the Belgian Promenade just upstream of the suspension bridge.

[13] The promenade was built along the Menai Strait from Ynys Tysilio (Church Island) to Carreg yr Halen and was completed in 1916.

This is a piece of common land set aside for the holding of an annual fair called Ffair Borth, a tradition dating back to 1691.

'Mae Ffair y Borth yn nesu, Caf deisen wedi ei chrasu, A chwrw poeth o flaen y tân, A geneth lân i'w charu.'

[19] The local board also took over the functions of the Llandysilio improvement commissioners, which had been established in 1879 to manage certain areas of former common land in the parish.
