The first of the villages consisted of a 25-arpent square, in which a five-arpent square (the "trait carré") was reserved for the church, presbytery and cemetery. The homes of the settlers located on the periphery of the Trait Carré and their trapezoidal plots of land form a star shape. The second village, which is semicircular due to lack of space, was established just to the south at Petite-Auvergne and the third was established in 1667 in Bourg-Royal, to the northeast. This particular arrangement is still visible from the air and is the hallmark of Charlesbourg.
