Construction of the foundation began on June 28, 1861,
the Feast of the Sacred Heart, and concluded in 1863. On December 8,
the Feast of the Immaculate Conception, with surrounding Chinese houses and streets decorated, a grand ceremony was held, attended by the
Viceroy of Liangguang, all senior
Mandarins, a detachment of 300
Manchu troops, all consuls in Canton as well as the missionaries and a score of priests. The bishop and the consul of France, Baron Gilbert de Trenqualye, delivered speeches. Two foundation stones were blessed and laid. The words "Jerusalem 1863" were engraved on the east one and "Roma 1863" on the west one, in reference to the
Catholic Church's origin in
Jerusalem in the east and headed on Earth by the Pope in
Rome in the west. One kilogram of soil taken from Rome and one stone from Jerusalem were laid under the respective foundation stones. The construction of the cathedral turned out to be very challenging, mostly because of its all-
granite structure and the lack of machinery, which meant the cathedral had to be built by hand. None of the Chinese workers at that time had seen a western cathedral before, not to mention had any experience of building one. Communication was another major problem when the French and the Chinese didn't speak each other's languages. The construction progress was slow for the first few years. Eventually the French employed a Chinese man named Cai Xiao () from
Jiexi County as
foreman. Cai had many years of experience in building stone houses in his hometown, which enabled him to bring in a lot of unique and creative methods. He barely left the site since being employed. The construction of the cathedral took most of his youth but was able to be finished in his lifetime. The cathedral was mostly funded by
Napoleon III. When bishop Guillemin met him in Paris in 1858, the emperor, urged by his wife
Eugénie, offered a personal grant of 500,000
francs. In 1873, a bill was passed in the
National Assembly of France with 491 ayes against 100 nays, allocating another 75,000 francs to the
Ministry of Foreign Affairs to be used on the cathedral. The cathedral was finished in 1888 after 25 years of construction. == Architecture ==
