The huge Cathedrale Notre-Dame-de-Strasbourg
At 142 metres, it was the world's tallest building from 1647 to 1874. It remained the tallest church in the world until 1880, when it was surpassed firstly by Cologne Cathedral and then the 161 metre Ulm Munster. Today it is the fourth-tallest church in the world.
