The first Europeans to inhabit what would become Canada were the French settlers of New France and Acadia. The initial settlements at Port Royal and Quebec City were most concerned with defence, against both First Nations and the English. For most of the early history of Quebec city it was dominated by the large fortress and outer walls. The city was divided into two sections. The Upper Town was home to the fortress, Intendant's house, and churches, these structures were built of stone in imitation of the Baroque architecture then popular in France. The Lower Town consisted of densely packed structures on narrow streets, and was the commercial centre and home to the workers.
