At the 2001 census it had a population of 699, increasing to 776 at the 2011 census.It is near the prehistoric monument of Bryn Celli Ddu which was constructed in the late Neolithic period. In the east of the community, by the Menai Strait, stands the country seat of the Marquess of Anglesey, Plas Newydd, parts of which date from the 14th century. The house has been owned by the National Trust since 1976. In the 16th century the poet Catrin ferch Gruffudd ap Hywel lived here. Her Welsh poems are preserved and they include an Awdl with a religious theme written in 1555.During the 2001 United Kingdom foot-and-mouth crisis, many sheep and cattle were slaughtered in the area.The village has its own community council and its county council representative is Hywel Eifion Jones, who has held the post since May 1999. Amenities include a post office, primary school (Ysgol Parc y Bont), and a 12-hole golf course.Probably the village's most famous son is Tecwyn Roberts (1925-1988), who became NASA’s first Flight Dynamics Officer with Project Mercury that put the first American into space. Roberts was born at Trefnant Bach cottage in Llanddaniel Fab and was a former pupil of Ysgol Parc y Bont. After serving as a member of the Avro Arrow project team and the Space Task Group, Roberts transferred to NASA where he eventually became chief of the Manned Flight Support Division, chief of the Network Engineering Division during the Apollo Program and later Director of Networks at Goddard Space Flight Center.The village was struck by an F1/T2 tornado on 23 November 1981, as part of the record-breaking nationwide tornado outbreak on that day.

Gaerwen railway station was situated on the North Wales Coast Line, serving as the junction for the Anglesey Central Railway line to Amlwch.

Bryn Celli Ddu Welsh pronunciation: [brʌn keːɬi ðɨː] is a prehistoric site on the Welsh island of Anglesey located near Llanddaniel Fab. Its name means 'the mound in the dark grove'. It was archaeologically excavated between 1928 and 1929. Visitors can get inside the mound through a stone passage to the burial chamber, and it is the centrepiece of a major Neolithic Scheduled Monument in the care of Cadw. The presence of a mysterious pillar within the burial chamber, the reproduction of the 'Pattern Stone', carved with sinuous serpentine designs, and the fact that the site was once a henge with a stone circle, and may have been used to plot the date of the summer solstice have all attracted much interest.

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.

Gaerwen (Welsh pronunciation) is a village on the island of Anglesey in the community of Llanfihangel Ysgeifiog. It is located in the south of the island 4 miles (6.4 km) west of Llanfairpwllgwyngyll and 4 miles (6.4 km) southeast of Llangefni . The A5 runs through the village, and the A55 runs just a few hundred metres north. According to the 2011 Census Gaerwen is now listed by the Office for National Statistics as Llanfihangel Ysgeifiog. The population of the community is 1,551. Gaerwen and Pentre Berw, Llangaffo are trio villages. The village gets its name from a combination of the Welsh words Caer (mutated to Gaer), meaning 'fortification', and Wen, meaning 'white'. There are no clear remains of a fort in the area, although the name was originally that of a farm in the area, before becoming the name for the entire settlement.

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".

The Old Church of St Nidan, Llanidan is a medieval church in the community of Llanidan, in Anglesey, North Wales, close to the Menai Strait. The first church on the site was established in the 7th century by St Nidan, the confessor of the monastery at Penmon, Anglesey, but the oldest parts of the present structure, are now closed and partly ruined, date from the 14th century. In about 1500 the church was enlarged by the addition of a second nave on the north side, separated from the earlier nave by an arcade of six arches. During 1839 till 1843 a new church was built nearby to serve the local community, partly due to the cost of repairing the old church. Much of the building was subsequently demolished, leaving only part of the western end and the central arcade. The decision was condemned at the time by Harry Longueville Jones, a clergyman and antiquarian, who lamented the "melancholy fate" of what he called "one of the largest and most important [churches] in the island of Anglesey". Other appreciative comments have been made about the church both before and after its partial demolition. After that a new church was opened, the old church was used as a chapel for funerals for a period of time. It has been restored by the owners of the adjoining house, Plas Llanidan, and is occasionally open to the public. The remaining parts of the church are a Grade II* listed building, a national designation given to "particularly important buildings of more than special interest", in particular because St Nidan's is regarded as "a good example of a simple medieval rural church, enriched by 15th-century additions".In the 12th century, Gerald of Wales said that the church possessed a curious stone carving similar to a thigh that would always return by the next day no matter how far away it was taken. A Norman earl, he recounted, had chained it to a large rock and thrown it into the sea, only for the stone to return to the church by the following morning. A sandstone chest containing bone fragments, possibly are relics of a saint, were found buried beneath the altar. The chest and the church's 13th-century font were relocated to the new church.

Llanfihangel Ysgeifiog (occasionally spelt Llanfihangel Esgeifiog or Llanfihangelesgeifiog) is a community (civil parish) and former ecclesiastical parish in Anglesey, Wales, east of Llangefni.

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.

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.

Pentre Berw () is a small village located on the island of Anglesey in north Wales. It lies about 2 miles (3.2 km) south of the county town of Llangefni, and next to Gaerwen.

HMS Conway was a naval training school or "school ship", founded in 1859 and housed for most of her life aboard a 19th-century wooden ship of the line. The ship was originally stationed on the Mersey near Liverpool, then moved to the Menai Strait during World War II. While being towed back to Birkenhead for a refit in 1953, she ran aground and was wrecked, and later burned. The school moved to purpose-built premises on Anglesey where it continued for another twenty years.
