Here is a photo I took of the interior of Notre-Dame Basilica in Montreal, Canada. It is one of the most beautiful Catholic churches I have ever seen. The basilica is built in the gothic style and it features very prominent architecture and well defined details. The basilica was built on top of a previous smaller church and the interiors were finally completed in the 1880s.
The most interesting feature is the intricate lighting which adds to the majestic feeling of being inside the building. Usually the church is busy with tourists since it is one of the most visited sites in Montreal.
