Chultem distinguished three styles in traditional Mongolian architecture: Mongolian, Tibetan and Chinese as well as combinations of the three. Among the first quadratic temples was Batu-Tsagaan (1654) designed by Zanabazar. An example of the ''ger''-style architecture is the lamasery Dashi-Choiling in Ulaanbaatar. The temple Lavrin (18th century) in the Erdene Zuu lamasery was built in the Tibetan tradition. An example of a temple built in the Chinese tradition is the lamasery Choijing Lamiin Sume (1904), which is a museum today. The quadratic temple Tsogchin in lamasery Gandan in Ulaanbaatar is a combination of the Mongolian and Chinese tradition. The temple of Maitreya (disassembled in 1938) is an example of the Tibeto-Mongolian architecture. Dashi-Choiling monastery has commenced a project to restore the temple and the  sculpture of Maitreya.
