Moriah Chapel commemorates John Elias, one of the most significant leaders of the Nonconformist movement in Wales. A notable member of his congregation was Richard Davies, the proprietor of a general store located in the town square.

The Davies family were astute businessmen and developed a substantial fleet of some 60 ships trading to North America and later to the Far East. Ships were built in Sunderland, Glasgow, Liverpool, Quebec and many other shipbuilding centres. The last two ships, named Afon Cefni and Afon Alaw, were built for the fleet in 1892 in Glasgow, and were over 2,000 tons. Robert Davies (Richard's son) left a fortune in 1905 in excess of £400,000 and some 4,000 acres of land in Anglesey.

An associate and fellow Methodist was James Donne, originally from Bala, who came to live in Llangefni and who was very much a mover and shaker and an astute businessman. Mr Donne was able to push forward the construction of a substantial project, persuading people like Robert Davies to provide substantial donations to the building funds.

The chapel was designed by Richard Thomas, but owing to excessive costs, the design was altered by Owen Moris Roberts in 1897, with a substantial donation to the cost being made by Richard Davies. Moriah Chapel is a wonderfully well balanced Classical building of local limestone.

Moving towards the square, the Bull Hotel can be seen on the right before turning left into the High Street. The street was made deliberately wide to cater for the cattle sale that would, in the early days, have been carried out in the street. A further sale of pigs, goats and poultry would have taken place in the square and horses sold in Church Street. The market, held twice weekly, is still an important feature of the town centre and is still located in the town square.

Turning right into Field Street one is immediately attracted to another Baptist chapel, Penuel, standing boldly at the end of the street. This again is a memorial chapel to another of the great nonconformists, Christmas Evans.

The original chapel, Cildwrn, has been taken over recently by the Evangelist movement. It is, however, a very early chapel and dates to 1781 and a first floor gallery was added in 1849. The ground floor window and door arrangement is typical of very early chapels.
