Nidan was a Welsh priest and, according to some sources, a bishop, in the 6th and 7th centuries. He is now commemorated as a saint. He was the confessor for the monastery headed by St Seiriol at Penmon, and established a church at what is now known as Llanidan, which are both places on the Welsh island of Anglesey. He is the patron saint of two churches in Anglesey: St Nidan's Church, Llanidan, built in the 19th century, and its medieval predecessor, the Old Church of St Nidan, Llanidan. Midmar Old Kirk in Aberdeenshire, Scotland, is also dedicated to him: Nidan is said to have helped to establish Christianity in that area as a companion of St Kentigern. St Nidan's, Llanidan, has a reliquary dating from the 14th or 16th century, which is said to house his relics.
St Cristiolus's Church, Llangristiolus is a medieval church near the village of Llangristiolus, in Anglesey, north Wales. The village, about 1 mile (1.6 km) from the building, takes its name from the church. Reputedly founded by St Cristiolus in 610, the present building dates from the 12th and 13th centuries. Alterations were made in the 16th century, when the large east window in Perpendicular style was added to the chancel – a window which has been described by one guide to the buildings of north Wales as "almost too big to fit" in the wall. Some restoration work took place in the mid-19th century, when further windows were added and the chancel largely rebuilt.
St Iestyn's Church, Llaniestyn is a medieval church in Llaniestyn, Anglesey, in Wales. A church is said to have been founded here by St Iestyn in the 7th century, with the earliest parts of the present building dating from the 12th century. The church was extended in the 14th century, with further changes over the coming years. It contains a 12th-century font and a 14th-century memorial stone to Iestyn, from the same workshop as the stone to St Pabo at St Pabo's Church, Llanbabo.
St Mary's Church, Pentraeth is a small medieval parish church in the village of Pentraeth, in Anglesey, north Wales. The date of construction is unknown, but is probably from some time between the 12th to 14th centuries. A church dedicated to St Mary was recorded here in 1254, but there is a tradition that there was an older church dedicated to St Geraint, an early British saint. Some medieval stonework remains in three walls of the building. A chapel was added to the south side in the 16th or 17th century. The church was altered and refurbished during the 19th century, including an extensive rebuilding by Henry Kennedy, the architect for the Diocese of Bangor, in 1882. St Mary's is still used for worship by the Church in Wales, and is one of three churches in a combined parish. Its conservation is specifically included in the aims of a Chester-based charity that promotes health and the arts in Anglesey and the north-west of England.
St Ffinan's Church, Llanffinan is a small 19th-century parish church built in the Romanesque revival style, in Anglesey, north Wales. There has been a church in this area, even if not on this precise location, since at least 1254, and 19th-century writers state that St Ffinan established the first church here in the 7th century. The church was rebuilt in 1841, reusing a 12th-century font and 18th-century memorials, as well as the cross at the eastern end of the roof.
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 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.
St Caffo's Church, Llangaffo is a 19th-century church, in the south of Anglesey, north Wales, about 5 miles (8.0 km) from the county town, Llangefni. It was constructed in 1846 to replace the previous medieval church in the village of Llangaffo. The new building includes a number of monuments from the old church, and has a spire which is a prominent local landmark. The churchyard has part of a stone cross dating from the 9th or 10th century, and some gravestones from the 9th to 11th centuries. It is dedicated to St Caffo, a 6th-century martyr who was killed in the vicinity.
St Gallgo's Church, Llanallgo is a small church near the village of Llanallgo, on the east coast of Anglesey, north Wales. The chancel and transepts, which are the oldest features of the present building, date from the late 15th century, but there has been a church on the site since the 6th or early 7th century, making it one of the oldest Christian sites in Anglesey. Some restoration and enlargement took place during the 19th century.
St Gwenllwyfo's Church is a 19th-century parish church near the village of Dulas, in Anglesey, Wales. It was built between 1854 and 1856 to replace an earlier church in the parish, also dedicated to St Gwenllwyfo, which needed repair and had become too small for its congregation. The new church was built nearer to the Llys Dulas estate, whose owner contributed £936 towards the total cost of £1,417, rather than near the area where many of the parishioners lived. In 1876, Sir Arundell Neave donated 27 panels of 15th and 16th-century stained glass that had once belonged to a Flemish monastery.
St Beuno's Church, Trefdraeth is the medieval parish church of Trefdraeth, a hamlet in Anglesey, north Wales. Although one 19th-century historian recorded that the first church on this location was reportedly established in about 616, no part of any 7th-century structure survives; the oldest parts of the present building date are from the 13th century. Alterations were made in subsequent centuries, but few of them during the 19th century, a time when many other churches in Anglesey were rebuilt or were restored.
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, 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.
St Edern's Church, Bodedern is a medieval parish church in the village of Bodedern, in Anglesey, north Wales. Although St Edern established a church in the area in the 6th century, the oldest parts of the present building date from the 14th century. Subsequent alterations include the addition of some windows in the 15th century, and a chancel, transept and porch in the 19th century, when the nave walls were largely rebuilt. Stained glass was also inserted into the windows of the chancel and transept.
St Eugrad's Church, Llaneugrad is an isolated church near the village of Marian-glas, in Anglesey, north Wales. A church was supposedly founded here by St Eugrad in about 605, although the earliest parts of the present structure are the nave, chancel and chancel arch, which date from the 12th century. A side chapel was added to the north in the 16th century, and some moderate restoration work was carried out in the 19th century. It contains a 12th-century font, a 13th-century carved stone depicting the crucifixion, and a memorial to one of the officers killed when the Royal Charter sank off Anglesey in 1859.
St Beuno's Church, Aberffraw is a 12th-century parish church in Anglesey, north Wales. A church was established in Aberffraw in the 7th century by St Beuno, who became the abbot of Clynnog Fawr, Gwynedd. St Beuno's may have been used as a royal chapel during the early Middle Ages, as the Princes of Gwynedd had a royal court in Aberffraw, as part of the Kingdom of Gwynedd. The oldest parts of the church date from the 12th century, although it was considerably enlarged in the 16th century when a second nave was built alongside the existing structure, with the wall in between replaced by an arcade of four arches. Restoration work in 1840 uncovered a 12th-century arch in the west wall, which may have been the original chancel arch or a doorway to a western tower that has been lost. The church also has a 13th-century font, some memorials from the 18th century, and two 18th-century copper collecting shovels.
St Mary's Church, Llanfair-yng-Nghornwy is a medieval parish church in the north-west of Anglesey, north Wales. The date of foundation of the church, which is in the village of Llanfair-yng-Nghornwy, is unknown, but the oldest parts date from the 11th or 12th century. It has twice been enlarged: in the 15th century, when the chancel was rebuilt, and in the 16th century, when a chapel was added to the south of the chancel, separated by three arches. The tower at the west end is from the 17th century. A south porch of unknown date has been converted into a vestry, and the church is now entered through the tower.
St Cynfarwy's Church is a medieval parish church in Llechgynfarwy, Anglesey, north Wales. The first church in the vicinity was established by St Cynfarwy in about 630, but no structure from that time survives. The present building contains a 12th-century baptismal font, indicating the presence of a church at that time, although extensive rebuilding in 1867 removed the datable features of the previous edifice.
St Mary's Church, Llanfair-yn-y-Cwmwd is a small medieval parish church near the village of Dwyran, in Anglesey, north Wales. The building probably dates from the 15th century, with some alterations. It contains a 12th-century carved stone font and a 13th-century decorated coffin lid. The bell is inscribed with the year of its casting, 1582. The historian Henry Rowlands was vicar of St Mary's in the late 17th and early 18th centuries. Maurice Wilks, who invented the Land Rover, is buried in the churchyard.
St Edwen's Church, Llanedwen, is a 19th-century parish church near the Menai Strait, in Anglesey, north Wales. The first church was founded here by St. Edwen in 640, but the present structure dates from 1856 and was designed by Henry Kennedy, the architect of the Diocese of Bangor. It contains some memorials from the 17th and 18th centuries and a reading desk that reuses panel work from the 14th and 17th centuries. The 18th-century historian Henry Rowlands was vicar here, and is buried in the churchyard. The church is on land that forms part of the Plas Newydd estate, home of the family of the Marquess of Anglesey since 1812 and owned by the National Trust. Some of the Marquesses of Anglesey, and some of their employees, are also buried in the churchyard.
St Ceinwen's Church, Cerrigceinwen, is a former parish church in the countryside of central Anglesey, north Wales. The present building dates from 1860, although the site has been used for worship since at least the 7th century. The doorway reuses some old carved gravestones, one from the 9th to 11th centuries, and another from the 12th century. The church grounds contain a well, once thought to have healing properties. The church and the well are both named after St Ceinwen, an early Celtic female saint.
St Peter's Church, Llanbedrgoch, is a small medieval parish church near the village of Llanbedrgoch in Anglesey, north Wales. The oldest parts of the building date from the 15th century; it was extended in the 17th century and restored twice in the 19th century. The doorway is decorated with carvings of two human heads, one wearing a mitre. The church contains a reading desk made from 15th-century bench ends, one carved with a mermaid holding a mirror and comb.
