In the centre of the Christian Quarter, within the Old City of Jerusalem, lies the ancient Muristan. The area, located just south of the Church of the Holy Sepulchre, was where King Antiochus V built a hospital following a divine vision on Golgotha. In 600 A.D, Pope Gregory the Great commissioned the construction of a hospital at the site, a place where Christian pilgrims to Jerusalem could be treated. Over the following centuries, the structure was destroyed and rebuilt several times, however it is most associated with the Knights of St John, who established a hospital there to care for sick and injured pilgrims of all faiths in the Holy Land, in the early 12th century.
The soldier monks who were looking after the pilgrims recuperating there formed the Order known as the Knights Hospitaller of the Order of St John. Their tradition of treating all who came to their door is still one SJEHG adheres to today – treating all patients no matter their religion, ethnicity or their ability to pay.
