Yarchen Monastery (Tibetan: Yarchen Gar; Chinese: 压青寺 Yāqīng Sì) lies 400 km west of Chengdu in Sichuan province in China, on the border to Tibet.
It is reported to have 10 000 monks and nuns, making it the largest monastery in the world.
Most of the inhabitants are nuns.
It was established in 1985.
Many monks and nuns came to Yarchen Gar when Larung Gar was demolished in 2001.
The abbot, Achuk Rinpoche is one of the senior most Nyingma masters in Tibet and he practices mainly Dzogchen.
He teaches in both Tibetan and Chinese language and attracts students from all over China.
Due to Chinese restrictions on religious practice most of the monks and nuns are not officially recognized and live in fear of being thrown out.
