Old Church of St Nidan, Llanidan

St Nidan's Church, Llanidan is a 19th-century parish church near the village of Brynsiencyn, in Anglesey, north Wales. Built between 1839 and 1843, it replaced the Old Church of St Nidan, Llanidan, which needed significant repair, providing a place of Anglican worship nearer to the village than the old church. Some items were moved here from the old church, including the 13th-century font, two bells from the 14th and 15th century, and a reliquary thought to hold the remains of St Nidan. The tower at the west end has been described as "top heavy" and looking like "a water tower".The church is still used for worship by the Church in Wales, one of five in a group of parishes in the south of Anglesey. It is a Grade II listed building, a national designation given to "buildings of special interest, which warrant every effort being made to preserve them", in particular because it is regarded as "a distinctive example of pre-archaeological gothic revival work." The 19th-century clergyman and antiquarian Harry Longueville Jones said that it had been built in a "debased barbarous style, showing neither architectural science nor taste".

Llanfair-is-gaer was an ecclesiastical parish in Caernarfon, Gwynedd: the parish church was St Mary's.

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.

Llanidan is a community in the south of Anglesey, Wales which includes the village of Brynsiencyn (Welsh pronunciation). The parish is along the Menai Strait, about 4 miles north-east of Caernarfon (across the strait). The parish church of St Nidan is near the A4080 highway, a little to the east of Brynsiencyn. The ruins of an earlier parish church survive.

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.

Perthi-Duon Burial Chamber is a Neolithic dolmen located to the west of Brynsiencyn, Anglesey, Wales.

Llanedwen is a village in the community of Llanddaniel Fab, Ynys Môn, Wales, which is 126.5 miles (203.6 km) from Cardiff and 208.8 miles (336 km) from London. St Edwen's Church, Llanedwen is located in the area.

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 Anglesey Sea Zoo (Welsh: Sw Môr Môn) is an aquarium and independent research and marine education centre on the south coast of Anglesey island in North Wales. Located just outside the village of Brynsiencyn, Anglesey Sea Zoo claims to be the largest aquarium in Wales and displays over 150 native species.

Afon Seiont (Welsh, meaning River Seiont in English) is a river in Gwynedd, Wales which runs into the Menai Strait. Its source is the outflow of Llyn Padarn near Llanberis, and it flows out in a generally northwest direction. Between the outflow and the village of Llanrug it is known as the Afon Rhythallt, changing its name just after the village. Its mouth is in the town of Caernarfon, forming a natural harbour as it flows out into the Menai Strait. The Afon Nant Peris provides the main inflow into Llyn Peris which then drains into Llyn Padarn with the addition of the waters of the Afon Arddu which drains the northern slopes of Snowdon. The name of the Roman fort of Segontium, near Caernarfon, is based on the Latinised form of the name 'Seiont'. In the Brythonic language *seg-ontio translates as "strong place".

St Deiniol's Church, Llanddaniel Fab, is a small 19th-century parish church in the centre of Llanddaniel Fab, a village in Anglesey, north Wales. The first church in this location is said to have been established by St Deiniol Fab (to whom the church is dedicated) in 616. He was the son of St Deiniol, the first Bishop of Bangor. The current building, which is in Early English style, incorporates some material and fittings from an earlier church on the site, including the font and an 18th-century memorial in the porch. The vestry door has medieval jambs and the keystone of its arch, which is also medieval, is a carved human face. Some parts of the nave walls may also come from a previous building here. The church is no longer used for worship, and the village is now served by a church in Llanfairpwll. As of 2011, the building (without the surrounding grounds) was for sale. It is a Grade II listed building, a national designation given to "buildings of special interest, which warrant every effort being made to preserve them", in particular because it is regarded as "a good example of a simple 19th-century rural church".
