Assumption Cathedral, Staraya Ladoga Assumption Cathedral, Staraya Ladoga Assumption Cathedral, also Dormition Cathedral () in the selo of Staraya Ladoga, Volkhovsky District, Leningrad Oblast, Russia is one of the oldest churches of Russia, dating from the second half of the 12th century. It is one of the few surviving pre-Mongol buildings in Russia, and the northernmost one. The cathedral is the katholikon of the female Assumption Monastery, one of the several monasteries in Staraya Ladoga, and is located on the left bank of the Volkhov River. The building was designated an architectural monument of federal significance (#4710028015). Staraya Ladoga was the first seat of
Lake Ladoga "neva" "bog, quagmire". Ancient Norse sagas and Hanseatic treaties both mention a city made of lakes named Old Norse Aldeigja or Aldoga. Since the beginning of the 14th century this hydronym was commonly known as "Ladoga". According to T. N. Jackson, it can be taken "almost for granted, that the name of Ladoga first referred to the river, then the city, and only then the lake." Therefore, he considers the primary hydronym Ladoga to originate in the eponymous inflow to the lower reaches of the Volkhov River whose Finnic name was Alodejoki (corresponding to modern ) "river of the lowlands".
