St Mary's Church, Rhodogeidio is a small medieval church, dating from the 15th century, near Llannerch-y-medd, in Anglesey, north Wales. It served as a chapel of ease to another church in the area, St Ceidio's. Some restoration work was carried out in the 19th century, but St Mary's has since fallen into disuse and is now largely in ruins. 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 "a late Medieval church of exceptionally simple character", and is virtually unaltered despite its poor condition. One writer has said that St Mary's "has the distinction of probably being the most isolated church in Anglesey".

St Pabo's Church, Llanbabo is a medieval church in Llanbabo, in Anglesey, North Wales. Much of the church dates to the 12th century, and it is regarded as a good example of a church of its period that has retained many aspects of its original fabric. The church houses a tombstone slab from the 14th century, depicting a king with crown and sceptre, bearing the name of Pabo Post Prydain, the reputed founder of the church. However, there is no evidence that Pabo, a 5th-century prince, lived in the area and the tradition that he founded the church has little supporting basis. The church is still in use, as part of the Church in Wales, although services are only held here occasionally. It is a Grade II* listed building, a designation given to "particularly important buildings of more than special interest", because it is a medieval church that has been little altered.

St Ceidio's Church, Rhodogeidio is a rural 19th-century church near Llannerch-y-medd, in Anglesey, north Wales. It was built using materials from the 14th-century church that previously stood on the site, which has been used for Christian worship since some time in the 7th century. The present building, which contains an east window dating from the 14th century and a 15th-century font, is no longer used for services, but has been looked after by local people. 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 "unusual in being built closely to the form and detail of its Medieval predecessor." Two 19th-century writers thought that the church was in a "dreary spot", but a 2006 guide to Anglesey churches describes it as being in a pleasant location with good views.

It lies within the community of Tref Alaw.The ancient church of St Pabo, Llanbabo is dedicated to Saint Pabo: possibly Pabo Post Prydain, one of the leaders among the Britons of the Hen Ogledd following the withdrawal of the Roman legions. He is said to have founded a church here in 460, upon the site of which the present one is built, and to have been buried here along with his daughters. A 14th-century effigy of Pabo, along with the words HIC JACET PABO POST PRUD CORPORS ... TE ... PRIMA, is found on a stone in the church.Llyn Alaw lies nearby.

Rhosgoch (; meaning: Red Moor) is a small village in the north of the island of Anglesey, Wales, about 3.5 miles (5.6 km) to the south-west of Amlwch. It is in the community of Rhosybol. A short distance to the west of the village is the small lake Llyn Hafodol and a mile to the south is Anglesey's largest body of water the reservoir Llyn Alaw (Water Lily Lake).The village once had a station on the Anglesey Central Railway. Although the tracks still exist, no train has run on them since 1993. Also connected to the railway, was a short south-west facing spur that led to an oil terminal. This was linked to a floating dock in the sea off of Amlwch, where super-tankers could dock in all tides and feed oil via Rhosgoch and a pipeline to Stanlow oil refinery. This operation lasted for 16 years between 1974 and 1990.The first tornado of the record-breaking 1981 United Kingdom tornado outbreak, an F1/T2 tornado, touched down close to Rhosgoch at around 10:19 local time on 23 November 1981.

Rhosgoch railway station was situated on the Anglesey Central Railway line from Gaerwen to Amlwch. It had a small platform on the Down (west) side of the track, the original wooden building on which was replaced in 1882 by a brick building. To the north of the platform was a small goods yard. In the 1970s a private siding was constructed to connect the line to the Shell Oil Tank Farm nearby.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 goods yard and Tank Farm have been removed but the sidings and station building remains, the former owned by Isle of Anglesey County Council and the latter by a private individual.
