"Notre-Dame Basilica of Montréal A church—or, at least, a small chapel—has stood on the site of the Basilica of Notre-Dame since shortly after Ville-Marie (Montréal's predecessor) was founded in 1642. The current building, however, dates to 1829 and was constructed in a soaring Gothic Revival style. At the time, that aesthetic choice raised some eyebrows—Gothic designs were associated more with Protestant churches than Roman Catholic ones. (Perhaps the fact that the architect was an Irish-American Protestant didn't help the situation.) Whatever initial resistance there was evaporated in the face of the beauty of the completed building. In the decades that followed, Gothic became the popular choice for churches in Canada of every denomination in large part because of Montréal's basilica. In the 1870s, in what was perhaps a case of gilding the lily, the basilica became even more stunning when its interiors were painted in bright colors to resemble Paris 's Ste-Chapelle."
