The Notre-Dame Basilica of Montreal is a premier example of Gothic Revival architecture located in the historic Old Montreal district. Designed by architect James O'Donnell and constructed between 1824 and 1829, the interior features extensive use of polychromatic woodwork and gold-leaf carvings. The vaulted ceiling is painted deep blue and decorated with gold stars, contrasting with the dark walnut furnishings. The Casavant Frères pipe organ, installed in 1891, contains over 7,000 individual pipes. The basilica remains an active Roman Catholic parish and houses a collection of religious art dating back to the French colonial period. An immersive light and sound show, 'Aura,' is frequently presented within the sanctuary to highlight the intricate architectural details. The building replaced an earlier seventeenth-century chapel that had become too small for the growing parish population. The twin towers are named 'La Persévérance' and 'La Tempérance,' representing the virtues of perseverance and temperance.
