Roman conquest of Anglesey

Anglesey (; Welsh: (Ynys) Môn [ˈənɨs ˈmoːn]) is an island off the north-west coast of Wales. It forms a principal area known as the Isle of Anglesey, that includes Holy Island across the narrow Cymyran Strait and some islets and skerries. Anglesey island, at 260 square miles (673 km2), is the largest in Wales, the seventh largest in Britain, largest in the Irish Sea and second most populous there after the Isle of Man. Isle of Anglesey County Council administers 276 square miles (715 km2), with a 2011 census population of 69,751, including 13,659 on Holy Island. The Menai Strait to the mainland is spanned by the Menai Suspension Bridge, designed by Thomas Telford in 1826, and the Britannia Bridge, built in 1850 and replaced in 1980. The largest town is Holyhead on Holy Island, whose ferry service with Ireland handles over two million passengers a year. The next largest is Llangefni, the county council seat. From 1974 to 1996 Anglesey was part of Gwynedd. Most full-time residents are habitual Welsh speakers. The Welsh name Ynys Môn is used for the UK Parliament and Senedd (Welsh Parliament) constituencies. The postcodes are LL58–LL78. It is also a historic county of Wales.

St Caian's Church, Tregaian, also known as St Caean's Church, Tregaean, is a small medieval church dating from the 14th century in Anglesey, north Wales. It is dedicated to St Caian, a Christian from the 5th or 6th century about whom little is known. The building contains a late 14th-century east window and a late 15th-century doorway. The churchyard contains the grave of William ap Howel, who died in 1581 at the age of 105, leaving over forty children between the ages of 8 and 89 and over three hundred living descendants. The church is still used for worship by the Church in Wales, and is one of three churches in a combined parish. It is a Grade II* listed building, a national designation given to "particularly important buildings of more than special interest", in particular because it is regarded as "an excellent late Medieval rural church".

Llangwyllog (Welsh pronunciation) is a small village and ancient parish in the centre of Anglesey, Wales. It is found three miles to the north of the island's capital, Llangefni, and two miles north of Llyn Cefni, the island's second largest body of water. The settlement was once far more important than it is today, reaching a population of 277 in 1821, whereas the 1971 census showed only 75 people living there. The Anglesey Central Railway used to operate a station in the village until its closure in 1993. The tracks however still run through the village and there is a significant railway cutting in the village. The parish church is St Cwyllog's Church, Llangwyllog; the first church here was founded by St Cwyllog in the 6th century. One historic event said to have taken place here in 1134 was a battle between Owain Gwynedd, the first king of Wales, and the armies of the Erse, Manx and Norsemen, who had invaded the island. In the end the Welsh leader was triumphant.

Llyn Cefni is a small reservoir in the centre of Anglesey, Wales which is managed by Welsh Water and Hamdden Ltd, while the fishery is managed by the Cefni Angling Association. The reservoir is located just 1 kilometre (0.6 mi) northwest of the island's county town of Llangefni.

Llangwyllog railway station was situated on the Anglesey Central Railway line from Gaerwen to Amlwch. The single storey station building with ticket and waiting room was located on the Down (west) side and opened in 1865, the platform being extended in 1890. A small goods shed was located north of the main building. In 1914 a passing loop was installed at the station, the only one of the whole Anglesey Central line. Another platform was also installed in the year on the opposite side of the line which had a wooden shelter on it.The line between Llangefni and Llanerchymedd opened on 1 February 1866, Llangwyllog station opened the same day.All stations on the Anglesey Central line closed to passengers in 1964 as part of the Beeching Axe although freight works continued until 1993. The line is still in situ but the goods track and the passing loop has been lifted. The station building itself is now privately owned.

St Cwyllog's Church, Llangwyllog, is a medieval church near Llangwyllog, in Anglesey, north Wales. St Cwyllog founded a church here in the 6th century, although the exact date is unknown. The existence of a church here was recorded in 1254 and parts of the present building may date from around 1200. Other parts are from the 15th century, with an unusual annexe (possibly intended for use as a schoolroom) added in the 16th century. The church contains some 18th-century fittings, including a rare Georgian three-decker pulpit and reading desk. The church is still in use for worship by the Church in Wales, as one of seven churches in a combined group of parishes. It is a Grade II* listed building, a national designation given to "particularly important buildings of more than special interest", because it is regarded as a "good rural medieval church" with some features from the 15th century, as well as the 18th-century fittings.

Tre-Ysgawen is a hamlet in the community of Llanddyfnan, Ynys Môn, Wales, which is 135 miles (217.3 km) from Cardiff and 216.2 miles (347.9 km) from London.The name comes from the Welsh language: "Tre" meaning "homestead" and "ysgawen": "the elder tree".

Rhosmeirch (Welsh pronunciation) is a small village in Anglesey, Wales. It is in the community of Llangefni. It is located 1+1⁄2 miles (2.4 km) north of the county town, Llangefni, and half a mile east of the reservoir Llyn Cefni, with a village hall and a park.

The Dingle (Welsh: Nant y Pandy) is a nature reserve found just to the north of Llangefni, Anglesey, north Wales. Dingle is a common placename in the English language, which means "steep wooded valley", which describes it well. However, like many similar English names for natural attractions in Wales, e.g. Fairy Glen, the English name is recent and probably coined as tourism developed. The original Welsh name, still used by locals, is Nant y Pandy (Fulling Mill Brook), as there used to be a wool processing plant in the valley. The park is naturally divided into two parts, the wooded southern half and the northern half which is in a clearing. The main entrance is by St Cyngar’s Church where there is a car park. The reserve is 25 acres (10 ha) in area and is bisected by the Afon Cefni (River Cefni). It was formed by glaciers during the last ice age as they eroded the soft rock of the area. It gained its current name in the 1830s and was designated as a local nature reserve in 1995, although there has been a blanket tree preservation order in place since 1971. In 2003 the reserve was granted £122,000 for major improvements including better disabled access, boardwalks and tree sculptures. It was awarded the UK MAB Urban Wildlife Award For Excellence in 2004 thanks to this work. The boardwalks allow visitors to make their way north to Llyn Cefni, travelling parallel to the disused tracks of the Anglesey Central Railway. Red squirrels can be found in the area.According to some stories, pumas live in Nant y Pandy. In the 1970s big cats were banned from being pets, so many people came to North Wales to let their cats loose.

Hendre is an area in the community of Llanddyfnan, Ynys Môn, Wales, which is 133.8 miles (215.3 km) from Cardiff and 214.9 miles (345.9 km) from London.

Also, however, it is one of nine constituencies in the North Wales electoral region, which elects four additional members, in addition to nine constituency members, to produce a degree of proportional representation for the region as a whole. It was represented from 1999 by Ieuan Wyn Jones, the former leader of Plaid Cymru. Jones resigned from the Assembly on 20 June 2013, triggering a by-election, which was held on 1 August 2013. Plaid Cymru's candidate Rhun ap Iorwerth comfortably held the seat for the party with a majority of over 9000 votes.
