From Jerusalem Architecture by David Kroyanker

Once the Crusaders reached the Holy Land, they built churches—like the Church of St. Anne (shown here), supposedly erected on the site of the house where Anne and Joachim gave birth to the Virgin Mary. An earlier, much smaller structure was built on the site in the Byzantine period (fifth century A.D.) to be used as a convent for nuns. The first Crusader king, Baldwin I, banished his Armenian wife to this convent. One of the daughters of Baldwin II (1118–1131), Yvetta, also lived in the convent for a short time. The site thus enjoyed royal patronage—especially that of Baldwin II’s other daughter, Queen Melisende (1131–1152), who built the Church of St. Anne around 1140. In the 19th century the Ottoman sultan donated the church, which had fallen into disrepair, to the French government, which substantially restored the building.
