 The Taltsy Museum (), located on the Angara South of Irkutsk, is an open-air museum of Siberian traditional architecture.Numerous old wooden buildings from villages in the Angara valley, which have been flooded after the construction of the Bratsk Dam and Ust-Ilimsk Dam, have been transported to the museum and reassembled there.One of the centerpieces of the collection is a partial recreation of the 17th-century "ostrog" (fortress) of Ilimsk, which consists of the original Spasskaya Tower and the Church of Our Lady of Kazan transported from the flooded "ostrog" in the mid-1970s, to which an exact modern copy of another tower of the "ostrog" and the Southern wall of the fortress were added in the early 2000s.
