St Plegmund’s Well isn’t in Wales, it is in Cheshire, close to St Peter’s Church, Plumstall near the village of Mickle Trafford, just east of Chester, but I just had these photographs from this year’s Well Dressing ceremony. Each time I have visited the well it has been dry, although there are reports of water having been in the well and its use for baptism in the 20th century.
It is named after Plegmund, who is believed to have lived as a hermit in the area in the late 9th century. He was known as a scholar, and was summonded to the court of Alfred the Great as a part of Alfred’s project to reintroduce theological scholarship in England sometime before 887. He was elected Archbishop of Canterbury by Alfred in 890 and and travelled to Rome to be consecrated by Pope Formosa. He contnued as Archbishop until his death 923 (some sources suggest 914). He oversaw much of the recovery of the church in England following the Viking invasions and restored a number of bishoprics in Viking held regions that had been vacated and left unfilled. Alfred the Great died in 899 and was succeeded by his son Edward the Elder who was crowned by Plegmund.
His feast day is August 2nd, although the well dressing, which is a recently introduced event no longer coincides with this date.

As I live near to this well,I delight in taking people when on a bike ride to visit the well.Usually it has a iron fence but this is removed when it is dressed. I have pictures from the dressing this year (2012) which had a jubilee and comonwealth theme, email me and I can send you a copy.
I thought I read that the story was that a sailor was wrecked in the area,as it was all sea,and he prayed that if he was spared he would build a church? There is a local history site I saw that on – http://www.mickletrafford.org.uk/history.php – about halfway down.
Lovin the blog, got interested in local history after I left school;and am going to Anglesley next week,where I hope to find St Gwenfaen’s well!
thanks for your comments – have emailed.
