Having grown up in Norwich, I was interested to hear that there's a scaled-down replica of the Catholic Cathedral near Lettefrack, Ireland. It looks a bit different as obviously not everything could be scaled down, but it's a pretty good effort - made in the local green Connemara stone:

And for comparison, here's the real deal - with a bit of wikipedia info added in as it's fair to say the Catholic Cathedral is the lesser-known of Norwich's seats of worship:

The Cathedral, located on Earlham Road, was constructed between 1882 and 1910 to designs by George Gilbert Scott, Jr. as a parish church dedicated to John the Baptist. The funds for its construction were provided by Henry Fitzalan-Howard, 15th Duke of Norfolk. In 1976 it was consecrated as the cathedral church for the newly erected Diocese of East Anglia and the seat of the Bishop of East Anglia.

Its cathedral-based fame is surpassed by the Church of England Cathedral, a Norman Gothic masterpiece, built from 1096-1145 and the second tallest cathedral in the England, at 315 feet. It's a good job no-one tried scaling it down though, as the famous cloisters would lose some of their charm if you had to crawl through them:

Still, that might seem positively spacious to the congregation of
Bremilham Church, Wilshire - the smallest Church in the UK.
