The first open-air museum in the republic was founded in 1977 in the village of Cherkekh of the Tatta ulus. The idea of the museum belongs to the national writer of Yakutia Dmitry Sivtsev-Suorun Omolloon, in honor of whom the historical and memorial complex was named. 20 historical and architectural monuments of wooden architecture of the 19 - early 20 centuries are collected here. Almost every of these exhibits, like the territory itself, requires some efforts. The museum needs considerable financial investments. In 2012-2013, ALROSA allocated 42 million rubles for the reconstruction of museum collection through the Future Generations Fund.
