One of the most unique and beautiful places in St. Petersburg is the Church of the Savior on Spilled Blood. It's built in the place where Emporer Alexander II was murdered in 1881, hence the name. Sadly, the church was looted and badly damaged in the Revolution of 1917. During that time it stored vegetables and was nicknamed 'Saviour on Potatoes'. It is mostly restored now and it is absolutely breathtaking. The inside is covered entirely of mosaics.
