St. Nicholas Russian Orthodox Church is a small onion-domed building perched on a hillside above downtown Juneau, dating from 1894 and the oldest original church building in Southeast Alaska. The octagonal structure is topped with a distinctive copper-clad dome and holds icons, vestments, and liturgical objects from the Russian colonial period. The interior is richly decorated in traditional Orthodox style.
The church is still an active parish and welcomes visitors during limited hours. It stands in the Chicken Ridge historic district, a short walk uphill from the waterfront, and the approach gives good views over the Gastineau Channel. The building is listed on the National Register of Historic Places.
