The interior of this marvellous 1743 cathedral, which has been beautifully restored and repainted both outside and in, is one of the most gilded in the city. The grand gates bear the imperial double-headed eagle in vast golden busts, reflecting the fact that the cathedral was built on the site where the Preobrazhensky Guards (the monarch’s personal protection unit) had their headquarters. Architect Vasily Stasov rebuilt the cathedral from 1827 to 1829 in the neoclassical style. It is dedicated to the victory over the Turks in 1828–29; note the captured Turkish guns in the gate surrounding the cathedral.
