One place in Norwich which I keep meaning to go and see inside, is the Cathedral Church of St John the Baptist.

The building is beautiful from the outside, and I am interested in learning more about it and the format of the Services/Mass etc…
It was completed only in 1910, and designed by George Gilbert Scott, Jnr, in a particularly good example of the gothic revival style which was popular at the time in this country. It was not built, originally, as a cathedral, but as the parish church of Norwich. It remained a parish church until 1976.
I must go there and see it properly once the weather is warmer. If you are interested in finding out more about the place, then do check out their website which I have added below.
