Our Lady of the Sacred Heart Church, Yerkalo

Our Lady of the Sacred Heart Church, commonly referred to as Catholic Church of Yerkalo or Yanjing Catholic Church, is a Catholic church building located in Yerkalo (, lit. 'salt pit'), a village between 2650 and 3109 meters above sea level at the southern end of Markham County (Chamdo, Tibet Autonomous Region) in present-day China. It has been subjected to the control of the state-sanctioned Chinese Catholic Patriotic Association since 1957.

History
It was founded as a chapel in 1865 by Félix Biet and Auguste Desgodins, French missionaries of the Paris Foreign Missions Society, and dedicated to Our Lady of the Sacred Heart, patroness of the parish of Yerkalo. The church is referenced in Adrien Launay's Histoire de la Mission du Thibet as Chapelle de Notre-Dame du Sacré-Cœur. The mission of Yerkalo was based in Xinjiang but some of its missionaries opted to proselytize in Tibet. Within a few years, Tibetan marauders supported by Buddhist lamas killed 10 priests and destroyed all but one Catholic mission which was based in Yerkalo. Bringing with them thirty-five of their faithful, having been expelled from the main mission of Bonga in Yerkalo, conquered by the Qing dynasty, were legally established in some plots of land with the complicity of the population and silence of local officials. Historically, China and Tibet disputed the possession of the Yerkalo saline wells, which passed from one side or the other of the Sino-Tibetan border. Finally, in 1932, the village was placed under the Tibetan Government in Lhasa. In 1939, the parish of Yerkalo received devotional statues of Our Lady of the Sacred Heart and of Saint Thérèse of the Child Jesus.

According to the Xinhua news agency, the establishment of a small Catholic parish in Tibet was not an easy task. Enmity from the local Tibetan Buddhist monks from the Karma Gon Monastery culminated in the killing of one of Father Biet's successors, Maurice Tornay in August 11, 1949.

Architecture
The exterior of the church features traditional Tibetan design while the interior has European Gothic designs. The church holds weekly services in the Tibetan language. As of 2014, the church had one priest, two sisters and serves a estimated 559 worshippers around the area.
