So what is so interesting about the roofs of Brecon? You might well ask. I think the church is the Roman Catholic Church of St Josephs, but the interesting bit to me, as an ex-builder is the gable of the building in the forefront of the church. It is covered in corrugated tin sheets painted both black and blue. This seems to be common in Brecon but to us Gogs, that is North Walians, it is very unusual.
