You may spot Feodorovsky Cathedral across town before you actually find this amazing religious building. Peek inside if it's open or just appreciate the facade from the street.
This principal church is located in Bol'shaya Kuz'minka, a place that has lots going for it! Catherine Palace and Park in Tsarskoye Selo, Alexander Palace, and Pavlovsk Palace and Park are other fine sightseeing opportunities close by when you're done at Feodorovsky Cathedral.
