10 incredible churches and cathedrals you have to visit in London
"Westminster Cathedral, or to give it it’s snappier full name 'the Metropolitan Cathedral of the Precious Blood of Our Lord Jesus Christ', is the second largest church building in London behind St Paul’s. It’s the largest catholic church building in England and Wales and former popes John Paul II and Benedict XVI both celebrated mass here, making it a hugely significant religious setting. Neo-byzantine in design, it’s also one of the prettiest churches in the capital and one of the most awe-inspiring to visit."
