The Basilica started modestly enough as a chapel erected by Samuel de Champlain in 1633. It was destroyed in 1640, and rebuilt in stone in 1650. During the next hundred years, the church was extended and promoted to a cathedral (the bishop or cardinal's church, head of a diocese). Mostly destroyed by the battles of 1759 (when the English overcame French forces to conquer Canada), it was rebuilt in 1771. Yet more destruction, this time by fire in 1922, resulted in yet another rebuilding in 1925. The interior, however, faithfully follows 18th century style. The remains of Cardinal Laval, beatified by Pope John Paul II in 1980, lie inside.
Looking down the main aisle of the Basilica, with a closeup of the altar.
The statue in the (unnamed) park in front of the Basilica. The statue is that of Elzear-Alexandre Taschereau, 1820 - 1898. He was the Catholic Archbishop of Quebec and the first Canadian Cardinal. He also played a part in the founding of Laval University.
This cathedral was the first Anglican Cathedral built outside the United Kingdom. Constructed in 1804, it is modelled after London's St. Martin's In The Field (at Trafalgar Square, if I recall correctly). The bell tower is 47m high, with 8 bells. The Cathedral is only a few blocks from the Catholic Basilica. Note the craft stalls along the left hand side - the street on that side also has a number of vendors.
Holy Trinity's altar. Not quite as decorated as the Catholic one.
And, of course, it has a decent sized organ and choir loft at the rear.
