The cathedral is located in the most lively part of the city, with the greatest environment. This former collegiate church was founded in 966 and became a cathedral in 1802, replacing the great cathedral of Our Lady and St. Lambert which was destroyed during the revolution. It's a large Gothic building which was constructed after the original Church. There are 49 bells at the top of the tower. Don't forget to see the Christ of the Choir and the sixteenth century windows. The cathedral cloister has a valuable collection of treasures mostly from the old church.
