What has a lovely parish church deep in the Vale of Glamorgan in common with a Chinese restaurant in Cardiff?
I’ve been working on the quinquennial inspection of St Canna’s Church, Llangan, and saw something in the official listing. The exterior masonry is described as “vertical crazy paving.” I took a closer look.
It isn’t “crazy paving”. It’s polygonal stone masonry. Albeit much smaller in scale, it was inspired by the cyclopean walling classical
Greece, a rich hunting ground for source material in the days of 'the grand tour'. This is difficult, slow and expensive to build, and rather rare. Why would anyone choose this for a small rural church in a quiet village?
There is one other building in Glamorgan with the same distinctive polygonal walling: the one that now houses 'Summer Palace', the Chinese on High Street, Llandaff. That building is attributed to John Prichard's office, run by the Victorian Architect responsible for the restoration of Llandaff Cathedral and many churches across the diocese.
Prichard was born in Llangan. St Canna’s was almost certainly his childhood church — very likely the place where he was baptised. When the church was rebuilt in the mid‑19th century, he was the Diocesan Architect, working locally and deeply invested in the area.
So the unusual masonry suddenly makes sense. It was a gesture of significance — a way of giving his home parish something crafted, distinctive and rooted in the Victorian love of antiquity.
Putting all this together, we can now say with real confidence that John Prichard was almost certainly the architect of the rebuilding of St Canna’s, something that hitherto, was not known. And that the remarkable polygonal stonework is part of that personal story.
A lovely reminder that buildings sometimes carry the emotional fingerprints of the people who shaped them.
