St. Patrick's Basilica, Montreal (must see)

Built in 1847, during the Famine Migration from Ireland, Saint Patrick's is to Montréal's Anglophone Catholics what the Notre-Dame Basilica is to their French-speaking brethren. Among the country's purest examples of the Gothic Revival style, it was declared a historic monument and a National Historic site of Canada in 1996. A true feast for the eyes, you will gorge on its magnificent beauty and revel in the intricate ornate details imbued within.

Stained glass windows adorn the basilica throughout its corners and walls, and on a sunny day, the interior blossoms into a dazzling cornucopia of colour. The tall, slender columns are actually pine logs lashed together and decorated to look like marble, lending an air of majesty and solemness. Another major attraction is the large hanging lamp weighing 1,800 pounds, with six angels adorning the perimeter. You've never seen anything quite like it.

Why You Should Visit:
Not as opulent as Notre-Dame, but lovely on its own. It's lighter and brighter, with glorious woodwork and other details.
On a sunny day, the stained glass windows and Gothic architecture are textbook perfect and golden in hue.
Plus, the place is free to visit and you'll probably be the only tourist there, free to sit and contemplate.

Tip:
Visit after lunch and you might catch the organist practicing for upcoming services.
A side door is usually unlocked most days in case you can't get through the main entrance.
