Amarbayasgalant Monastery (Mongolian: Амарбаясгалант хийд, ᠠᠮᠤᠷ ᠪᠠᠶᠠᠰᠬᠤᠯᠠᠩᠲᠤ ᠬᠡᠶᠢᠳAmurbayasqulangtu keyid; Manchu: ᡠ᠊ᡵᡤᡠᠨ ᡝᠯᡥᡝ ᠰᡟ Urgun Elhe Sy, simplified Chinese: 庆宁寺; traditional Chinese: 慶寧寺; pinyin: Qìngníng sì) or the "azzaya", is one of the three largest Buddhist monastic centers in Mongolia.

[2] Tradition holds that while searching for an appropriate site to build the monastery, the exploratory group came across two young boys, Amur and Bayasqulangtu, playing on the steppe.

More likely, the location was chosen because it stood at the place where the lama's traveling Da Khuree (his mobile monastery and prime residence) was encamped at the moment of his death.

Unlike Erdene Zuu Monastery, which is an ensemble of temple halls of different styles, Amarbayasgalant shows great stylistic unity.

Many of the monks were executed by the country's Communist regime and the monastery's artifacts, including thangkas, statues, and manuscripts were looted, although some were hidden until more fortunate times.
