The exterior of the Notre-Dame de Québec Basilica Cathedral is relatively simple, with no elaborate reliefs or ornamentation. It also looks quite small from the front until you notice how far back it extends.
The interior, however, is another matter altogether.
Here is a closer view of the altar and its ornate, golden baldaquin (canopy of state).
The magnificent stained glass windows along the nave depict scenes from the life of Mary. Here are the three from the childhood of Jesus: his birth, his presentation at the temple, and his finding in the temple.
