Tengyeling, the seat of the Demo or Tengyeling incarnation line, was constructed during the seventeenth century after the Fifth Dalai Lama had assumed temporal power. Previously it was the most important of the regency seats in Lhasa, providing three regents of Tibet. Tengyeling's regency status was stripped in the early twentieth century by the Tibetan government after the Ninth Demo was discovered to have taken part in a plot to kill the Thirteenth Dalai Lama. The monastery's compound now consists of private dwellings and the Lhasa No. 1 Middle School.
