I’m a big fan of Moscow’s insane-looking St Basil’s Cathedral, with its colourful domes and irregular shapes. But if it’s a little too crazy for you, then you might prefer the Church of the Saviour on Spilled Blood (also known as the Cathedral of the Resurrection of Christ) in St Petersburg.

It’s also colourful, and covered with unusual domes, but in a slightly toned down way, and perhaps one more fitting a cathedral. Sitting next to one of St Petersburg’s many canals, the outside is extremely photogenic, and the kind of building you could stare at for hours. Inside it is jam-packed with incredible mosaics, and in fact these are main attraction for going inside these days, as it doesn’t function as a church. You’ll have to put plastic covers over your shoes so you don’t damage the floor, but you won’t have time to actually look at the floor – there are something like 7,000 square metres of mosaics on the walls and ceilings to enjoy.

If you asked me which of St Basil’s and the Saviour on Spilled Blood was my favourite church in Russia, I’d be really torn in making a decision – my best recommendation is that you absolutely must visit both, and then decide for yourself.
