Two blocks west of the Centennial Building is the cathedral. Built between 1844 and 1848, the church stood for more than 100 years as Alaska’s finest Russian Orthodox cathedral. When a fire destroyed it in 1966, the church had been the oldest religious structure from the Russian era in Alaska. Luckily the priceless treasures and icons inside were saved by Sitka’s residents, who immediately built a replica of their beloved church. There's a cathedral-run bookstore across the street.
