The Russian Compound had begun to develop in the early 19th century with the opening of the first hospital for pilgrims outside of the Old City walls. It hosted a market where local peddlers could sell their wares and services to pilgrims. In 1847 the first Russian Ecclesiastical Mission was sent to Jerusalem, which, in 1857, was officially inaugurated with the recognition from the Sultan of Turkey. Its purpose was to offer Russian pilgrims spiritual supervision, provide assistance, and sponsor charitable and educational work among the Orthodox Arab population of Palestine and Syria.
