The weighty mass of St. Isaac's Cathedral dominates the skyline of St. Petersburg. Its gilded dome, covered with 100 kg of pure gold, soars over 100 meters into the air, making it visible far out onto the Gulf of Finland. The Cathedral was commissioned by Alexander I in 1818 and took more than three decades to complete.
Its architect, August Monferrand, pulled out all the stops in his design, incorporating dozens of kinds of stone and marble into the enormous structure and lading its vast interior with frescoes, mosaics, bas-reliefs, and the only stained glass window in the Orthodoxy. By the time the cathedral was completed in 1858, its cost had spiraled to more than twenty million rubles - as well as the lives of hundreds of laborers. Both the exterior and the interior of the cathedral deserve prolonged observation, and the view from the dome is stupendous.
