The Monastery of San Pedro de Villanueva is a Romanesque monastery previously owned by the order of Benedictines. A church here supposedly was founded by Alfonso I the Catholic, son in law of Pelagius of Asturias. The remaining structures now date from later periods. In the 12th century, the monastery was built adjacent to the church. The buildings underwent substantial rebuilding after the 17th century. In 1835, the monastery was dissolved. In the present century, the monastery has become a national hotel, a Parador. The church is still in use.

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.
