The monastery has more than 100 resident monks and numerous Buddhist treasures, including a 26-metre (85 ft) statue of Avalokiteśvara made of gilded bronze and precious stones.

[1][2] The second Jebtsundamba Khutuktu established a tsanid (Buddhist education center) for the monks of Khüree (modern Ulaanbaatar) in the early 18th century.

Other buildings were added, including the Tsogchin dugan in 1839 and Ochirdari (Vajradhara) Temple in 1840, which has a silver and gold statue created in 1683 by Zanabazar.

The fifth, seventh, and eighth Jebtsundamba Khutuktus were interred at Gandan, though in 1855 they and their monks moved back to their original palace near the current city center.

To celebrate independence from Qing China in 1911, the eighth Jebtsundamba Khutuktu ordered the construction of Megzed Janraiseg (Eye-Opening Avalokiteśvara) Temple, completed in 1913 as Mongolia's tallest monastery building.

It has 70,000 Buddhist manuscripts and woodblock prints, including the 108-volume Ganjuur (precepts), 226-volume Danjuur (commentaries), and other works in Mongolian, Tibetan, and Sanskrit, some written in the "nine precious materials": gold, silver, turquoise, lapis lazuli, coral, pearl, mother-of-pearl, copper, and steel.
