This is the oldest church in Jerusalem, built in the mid-5th century and restored after the Persians destroyed it in 614. In the 11th century the merchants of Amalfi used the walls of the original building when constructing a new church, which became the cradle of the Knights Hospitaller. The present facade with the two small bell towers is a more recent addition. Now part of a Greek Orthodox monastery complex, it is accessed from Christian Quarter Rd.
