A Vision of Britain through Time provides the following description of Llanfair Is Gaer from John Marius Wilson's Imperial Gazetteer of England and Wales of 1870-72:

"LLANFAIR-IS-GAER, a parish in the [registration] district and county of Carnarvon; on the Menai strait and on the Carnarvon railway, 2¼ miles NE by N of [Caernarfon]. It contains the village of Brynffynon and the seaport village of Port-Dinorwig, the latter of which has a post office under Carnarvon. Acres: 2,474; of which 565 are water. Real property: £2,312. Population in 1851: 687; in 1861: 1,060. Houses: 201. The increase of population arose from the extension of slate quarrying; and 120 of that in 1861 were persons on board vessels. The property is divided among very few. Plâs-Llanfair is a chief residence.
"Port-Dinorwig is a shipping place for slates from the Snowdonian quarries; and is reached, through the parish, by a tram railway. A Roman camp was on the coast, immediately above the site of the church; and hence the name Llanfair-Is-Gaer, which signifies Mary church under a fort. Agricola crossed hence to Anglesey. The living is a [perpetual] curacy in the diocese of Bangor. Value: £77. Patron: the Bishop of Bangor. The church was rebuilt in 1865; is in the early English style, of local stone, faced with Newry granite and with Wrexbam stone; comprises nave, transept, and chancel, with vestry and bell-turret: and has a memorial window to the late J. G. Griffith. Esq.

There is no article for Llanfair Is Gaer in Wikipedia, but Port Dinorwig is described as follows:

"Y Felinheli, formerly known in English as Port Dinorwic, is a village and community beside the Menai Strait (Welsh: Y Fenai or Afon Menai) between Bangor and Caernarfon in Gwynedd, northwest Wales. The population of the village was 2,284 at the 2011 Census."

Slate tiles (shaped from the natural material) were a very popular roofing material for housing up until 1950. For the most part, they have been replaced by clay tiles or concrete tiles, but slate is still used.
