St Nidan's Church, Llanidan

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.

Caer Lêb is a Roman and mediaeval site on the Welsh island of Anglesey, west of Brynsiencyn. Its name means "Leaven Castle". It is a low-lying site near the Afon Braint with a double row of pentangular banks (some parts now levelled) and marshy ditches. The original entrance was on the east, other gaps are modern and caused by animals. Based on the excavation of a similar site elsewhere on Anglesey, it may date from the 2nd century BCE.Excavations in 1865 found structures within the enclosure, rectangular buildings on the east and a circular one on the south. Nothing of these can now be seen on the ground. Pottery from the 2nd century to the 4th century was found, and on the north side a layer of periwinkle shells and a mediaeval coin, under a layer of peat.There is a parking area, sufficient for 4-5 cars, by the roadside. A footpath goes southwest on a low ridge, some 2 metres above the Afon Braint, from Caer Lêb over stiles, past the site of the former stone circle of Tre'r Dryw Bach, some 800 metres to Castell Bryn Gwyn and on to the Bryn Gwyn stones and the A4080. 500 metres north-west along the road, by Pont Sarn Las (Green Causeway Bridge), the foundations of three round houses may be visible after a dry summer. A large settlement was recorded in the 19th century, and destroyed in the 1870s by agricultural improvement.

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.

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.

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".

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.

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.
