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.

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.

The Roman conquest of Anglesey refers to two separate invasions of Anglesey in North West Wales that occurred during the early decades of the Roman conquest of Britain in the 1st century CE. The first invasion of North Wales began after the Romans had subjugated much of southern Britain. It was led by the Provincial governor of Britannia, Suetonius Paulinus, who led a successful assault on the island in 60–61 CE, but had to withdraw because of the Boudican revolt. In 77 CE, Gnaeus Julius Agricola's thorough subjugation of the island left it under Roman rule until the end of Roman rule in Britain in the early 5th century CE. Anglesey, which was recorded in Latin as Mona and is still known as Môn in modern Welsh, was a place of resistance to Roman rule because it was an important centre for the Celtic Druids and their religious practices. After the conquest, there are no surviving Roman sources that mention Anglesey. Archaeologists have located a fort dated shortly after the first conquest near Cemlyn Bay; a trading settlement on the shore of the Menai Strait; and a village of huts huddled together on a hill for defence. In the last decades of Roman rule in Britain several military forts were built on the northern and western coasts to defend the island against Irish sea raiders. However, despite more than three centuries of Roman rule, archaeologists have found no evidence of major civic centres or villas on the island indicating that Romano-British culture lacked the influence it had in other parts of the Roman province of Britannia. The only Roman source for the island's two invasions is the Roman historian Tacitus. His last work The Annals, written as a history of the Roman Empire from Tiberius until Nero, mentions the first invasion by Suetonius Paulinus. The second invasion is detailed in Tacitus' work The Life of Gnaeus Julius Agricola, which was written to record and extol the life and accomplishments of his father-in-law. Tacitus may have used first-hand accounts from Agricola, who had been present with the Roman forces on both occasions.

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.

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.
