Notre-Dame Basilica is one of the most beautiful churches you'll ever witness with its gothic-esque design. Take it all in when you walk in, the spiral staircases that go to the 2nd floor, the lines and lines of pews, to the beautiful rerodus (wooden structure) behind the altar, and the stained glass that vibrantly shines on a semi-sunny day. There are tons of saints to pray to along the perimeter of the church, as well as two chapels, one near the front that is designated strictly for praying as well as a chapel near the rear which is utilized for smaller and private gatherings. Whether you are Catholic or not, this is worth checking out. The minute details that were put into this church are just amazing. And above all, be respectful as this is a holy house of god.
