The Church of St. Justinus of Nablus is a Roman Catholic church built in 1887. In 1907, the Rosary sisterhood arrived in Nablus and Rafidia to serve the Latin Patriarch of Jerusalem and assist the priest in the service of the church by visiting the families and teaching children. They also set up the Rosary Sisters School in Nablus and Rafidiya. As a result of the earthquake that hit Nablus in 1927, the church was damaged, but the Patriarchate renovated it and the church was reopened in 1931.
