The Basilica della Santissima Annunziata del Vastato construction was begun by the Franciscans in 1520 in a site previously occupied by the small church of Santa Maria del Prato, belonging to the Humiliati. Works were however halted in 1537, and in 1591 the Lomellini family continued the reconstruction, directed by Taddeo Carlone.
In the early 17th century the rich Baroque decoration was executed, with Andrea Ansaldo in charge of completing the works, and in particular the dome. The current Neoclassicist façade dates to 1830-1840s, designed by Carlo Barabino. The church was damaged by Allied bombings during World War II.
The decoration was employed the major Baroque studios and artists in Genoa in the 17th century.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
