The architecture of Mongolia is largely based on traditional dwellings, such as the yurt (Mongolian: гэр, ger) and the tent. During the 16th and 17th centuries, lamaseries were built throughout the country as temples which were later enlarged to accommodate a growing number of worshipers. Mongolian architects designed their temples with six and twelve angles and pyramidal roofs approximating the yurt's round shape. Further expansion led to a quadratic shape in the design of the temples, with roofs in the shape of pole marquees. Trellis walls, roof poles and layers of felt were eventually replaced by stone, brick beams and planks.
Mongolian artist and art historian N. Chultem identified three styles of traditional Mongolian architecture (Mongolian, Tibetan and Chinese), alone or in combination. Batu-Tsagaan (1654), designed by Zanabazar, was an early quadratic temple. The Dashchoilin Khiid monastery in Ulaanbaatar is an example of yurt-style architecture. The 18th century Lavrin Temple in the Erdene Zuu lamasery was built in the Tibetan tradition. The Choijin Lama Süm temple (1904), now a museum, is an example of a temple built in the Chinese tradition. The quadratic Tsogchin Temple, in Ulaanbaatar's Gandan monastery, combines Mongolian and Chinese traditions. The Maitreya Temple (demolished in 1938) was an example of Tibeto-Mongolian architecture. The Dashchoilin Khiid monastery has begun a project to restore this temple and the 24-metre (0.024 km) sculpture of Maitreya. Indian influences can also be seen in Mongolian architecture, especially in the design of Buddhist stupas.
