Erdene Zuu Monastery, near current-day Kharkhorin, built on the site of the old Mongol capital of Kharkhorum. The monastery was founded by Avtai Khan, Zanabazar's great-grandfather, in 1586. Avtai's tomb is the small white building on the left; the white building on the right is the tomb of Gombodorj, Avtai's grandson and Zanabazar's father.
Just uploaded some new material on my biography of Zanabazar. See The Life of Zanabazar. Zanabazar was the first of eight Bogd Gegens who ruled in Mongolia from 1639 to 1924. In addition to his role as the leader of Buddhism in Mongolia Zanabazar was also a world-class artist and polymath. More to come . . .
