St Edeyrn's Church

After the Norman Conquest, the church was rebuilt and became a chapel of ease to St Mary's. In the 12th century, it was recognised as the property of Tewkesbury Abbey, but was transferred to the Bishop of Llandaff in 1236, at which time it became a separate parish church. The clergy were appointed by the Chapter of Llandaff Cathedral. From 1671 to 1949 the parish was united with that of St Mellons.

The large Perpendicular windows were added in c. 1500, and the tower soon after. Five of the bells which the tower currently houses date from 1766. An extensive restoration occurred in 1888^[2] when the east chancel wall was completely rebuilt.

The church was transferred with St Mellons to the new Diocese of Monmouth after the creation of the Church in Wales. Llanedeyrn became a separate parish again in 1949 but in 1979 was renamed 'The Rectorial Benefice of Cyncoed'. St. Edeyrn's became a chapel of ease to All Saints' Church, Cyncoed. The benefice was renamed Cyncoed Ministry Area in 2017 and in 2022 was united with the former parishes of Rumney, Llanrumney and St Mellons to form East Cardiff Ministry Area. ^[3]

The church gained listed status in 1963,^[4] after which the machine-made tiles of the roof were replaced with Welsh slate. An additional bell was acquired in 1994.
