Aberystruth was an ancient ecclesiastical parish in Wales, located beside the north-west corner of the county of Monmouthshire against the border with Breconshire and between the parishes of Bedwellty and Trevethin. It extended from Beaufort in the north beyond Abertillery in the south.
Following a fire which destroyed the original St Peter's another church was built on the site circa 1857 and this was demolished in 1966. The present St Peter's Blaina dates from the late 1960s and today forms part of a larger ministry area served by clergy headed by the Rector of Ebbw Vale.
Aberystruth remained the official ecclesiastical name of the parish into the 1980s. Clergy were styled Rector of Aberystruth (Blaina) in Crockford's Clerical Directory but it had been obsolete in all other usages for decades. An attempt in recent years to restore the name for a ministry area which would have linked the Abertillery and Blaina parishes under one heading did not, in the end, succeed.
Aberystruth is now the eastern portion of the county borough of Blaenau Gwent
Parish bounds and Brynmawr
The 19th century settlement of Brynmawr spanned the original boundary of Monmouthshire (parish of Aberystruth) and Breconshire (parishes of Llanelly and Llangattock). At the southern end of Boundary Street Brynmawr you may still find the Boundary Stone marking the point where the three parishes met.
