The working model of the dome framework of the Church of the Holy Sepulchre, created by architects M. I. Eppingher from Russia and K. Moss from France, has been preserved at the Alexander Courtyard in Jerusalem thanks to the efforts of the chairman of the Historical IPPO, Nikolai Alexandrovich Vorontsov.

In 1834, the Church of the Resurrection (Church of the Holy Sepulchre) was severely damaged by an earthquake. In April 1862, the French and Russian ambassadors in Istanbul proposed to carry out the restoration of the church dome at the expense of France and Russia. The Sultan of the Ottoman Empire, Abdulaziz, expressed a desire to become a third party in this project. The Minister of Foreign Affairs of the Porte, Ali Pasha, welcomed the agreement reached between Western and Eastern Christianity during a meeting with the French ambassador L. Mustier and the Russian Prince A. B. Lobanov-Rostovsky. On September 5, 1862, a tripartite protocol was signed, according to which France, Russia, and Turkey agreed to immediately begin repairs on the dome and share the costs equally. The French and Russian sides appointed two architects to interact with the ambassadors and local Turkish authorities. One of the points of the protocol stated that the agreement does not grant new rights to Christian communities or the signing parties and does not affect previously acquired rights. France insisted on the removal of Greek inscriptions from the dome, while Russia and Turkey held a different view. In January 1866, the head of the Russian Spiritual Mission, Archimandrite Antonin (Kapustin), wrote to the Russian ambassador in Constantinople, N. P. Ignatiev: "The matter of the dome is finally nearing completion. My joy knows no bounds... Finally, the great eyesore, the living room between the domes of the Church of the Resurrection, will disappear... if only we could also eliminate the excessive disgrace of the sanctuary (toilets), tolerable for the dirty East, but intolerable for the rest of the Christian world."
