A notice on 29 August 1589 announced that the work had been completed: "A great palace in Piazza Lateranese has been brought to completion by Sixtus V." Fontana reapplied motifs of the Lateran Palace in the part of the Vatican Palace containing the present papal apartments, which he undertook later, and in his additions to the Quirinal Palace. The east front was finished under Clement XII, who surmounted it with his coat-of-arms in 1735. From the old Lateran constructions three monuments survive, two of which are located in one building built by Domenico Fontana in 1589 opposite the Lateran Basilica. These monuments are the Scala Santa and the Chapel of the Sancta Sanctorum. The Lateran remained in a suburban environment, surrounded by gardens and vineyards, until the growth of modern Rome in the later nineteenth century. Its site was considered unhealthy in Rome's malarial summers, however. In the late seventeenth century, Innocent XII located, in a part of it, a hospice for orphans who were set to work in a little silk manufactory. In the nineteenth century, Gregory XVI and Pius IX founded at the Lateran a museum of religious art and pagan culture for overflow from the Vatican galleries. In 1925 Pius XI established an ethnographic museum devoted to artifacts sent back by missionaries. On 11 February 1929, the Lateran Treaty was signed here, at last regulating the relations between the Holy See and the Italian State. It established that both the basilica and the Lateran Palace were extraterritorial properties of the Holy See, enjoying privileges similar to foreign embassies on Italian soil. During the Second World War, the Lateran and its related buildings provided a safe haven from the Nazis and Italian Fascists for numbers of Jews and other refugees. Among those who found shelter there were Alcide De Gasperi, Pietro Nenni, Ivanoe Bonomi and others. The Daughters of Charity of Saint Vincent de Paul and the sixty orphan refugees they cared for were ordered to leave their convent on the Via Carlo Emanuele. The Sisters of Maria Bambina, who staffed the kitchen at the Pontifical Major Roman Seminary at the Lateran offered a wing of their convent. The grounds also housed Italian soldiers. Fathers Vincenzo Fagiolo and Pietro Palazzini, vice-rector of the seminary, were recognized by Yad Vashem for their efforts to assist Jews. Pope John XXIII returned to the palace some pastoral functions by fixing here the seat of the vicariate and offices of the Diocese of Rome.
