Cathedral of Christ the Saviour
Voronikhin's nephew, Nikolay Ilyich Voronikhin, was an architect based in Ryazan. He inherited Andrey Voronikhin's archive; Ascension Cathedral in Kasimov (photo) by Nikolay Voronikhin is remotely based on Andrey Voronikhin's unrealized draft for Cathedral of Christ the Saviour in Moscow.
