Griffith's Crossing railway station was a former railway station located on the Bangor and Carnarvon Railway about a mile and a half south west of Port Dinorwic (now Y Felinheli), Gwynedd, Wales. It was opened in June 1854 with one platform and a single storey station building made of local stone with a booking office and waiting room. When the line was doubled in 1872, a second platform was constructed with a simple waiting shelter on it, made of similar materials to the main building. The two 320 ft platforms were connected by a level crossing. To the west was a small siding with a ramp. The station closed to passengers on 5 July 1937 when the platform and station buildings were demolished. Goods traffic continued to use it until 6 July 1964.On 13 November 1911 the royal train stopped at the station and its passengers embarked in order to travel to Caernarfon Castle so that the future Edward VIII could be Investitured. For the event additional temporary wooden buildings were erected and a canopy put up. The royal train stopped near the station again on 1 July 1969 for the investiture of Prince Charles. By this time, as the station was closed and demolished a temporary platform and buildings were erected. The site of the station was partly covered following the improvement and widening of the A487. However the station master's house still stands.

Menai is the name of an electoral ward in the town of Caernarfon, Gwynedd, Wales. As the name suggests, it borders the Menai Strait. The ward elects councillors to the town council and Gwynedd Council.

The Menai Strait (Welsh: Afon Menai, the "river Menai") is a narrow stretch of shallow tidal water about 25 km (16 mi) long, which separates the island of Anglesey from the mainland of Wales. It varies in width from 400 metres (1,300 ft) from Fort Belan to Abermenai Point to 1,100 metres (3,600 ft) from Traeth Gwyllt to Caernarfon Castle. It then narrows to 500 metres (1,600 ft) in the middle reaches (Y Felinheli and Menai Bridge) and then it broadens again. At Bangor, Garth Pier, it is 900 metres (3,000 ft) wide. It then widens out, and the distance from Puffin Island (Welsh: Ynys Seiriol) to Penmaenmawr is about 8 kilometres (5.0 mi).The differential tides at the two ends of the strait cause very strong currents to flow in both directions through the strait at different times, creating dangerous conditions. One of the most dangerous areas of the strait is known as the Swellies (or Swillies – Welsh Pwll Ceris) between the two bridges. Here, rocks near the surface cause over-falls and local whirlpools, which can be of considerable danger in themselves and cause small boats to founder on the rocks. This was the site of the loss of the training ship HMS Conway in 1953. Entering the strait at the Caernarfon end is also hazardous because of the frequently shifting sand banks that make up Caernarfon bar. On the mainland side at this point is Fort Belan, an 18th-century defensive fort built in the times of the American War of Independence (1775–1783). The strait is bridged in two places: the Menai Suspension Bridge (Welsh: Pont Grog y Borth) carrying the A5, and Robert Stephenson's 1850 Britannia Tubular Bridge (Welsh: Pont Britannia or Pont Llanfair). Originally the Britannia carried rail traffic in two wrought-iron rectangular box spans but after a disastrous fire in 1970, which left only the limestone pillars remaining, it was rebuilt as a steel box girder bridge, and now carries both rail and road traffic (A55). Between the two bridge crossings there is a small island in the middle of the strait, Ynys Gorad Goch, on which are built a house and outbuildings and around which are the significant remains of fish traps, no longer used.

The Caernarfon Mithraeum is a Mithraic temple or Mithraeum. It was located 137 meters north-east of the Roman castram of Segontium on the outskirts of modern Caernarfon in Gwynedd, Wales. The remains were discovered by accident on 2 April 1958 and excavated by the National Museum of Wales in August of the following year under the direction of George Boon. The site was found to be already damaged by a sewer trench which cut across the anteroom and had removed part of the southeast corner, but the majority of the temple could be excavated. The excavators noted the site was quite marshy and this suggested that a stream had once flowed close to the temple at the bottom of the shallow valley. The marshy conditions caused the mechanical excavator to frequently fall into the excavation, causing further damage.
