Notre-Dame Cathedral in Tournai, Belgium

A really amazing church. It was built between the 12th and 13th centuries, at a time when the cathedral architecture in Europe was moving from Romanesque to Gothic. The Tournai Cathedral itself is a transition from Romanesque to Gothic! You enter the massive pure Romanesque nave, you get to a transept that is early Gothic, and then the choir is pure Gothic. It's really incredible to see this. I've been to many of the most impressive Gothic cathedrals, and I've seen a lot of Romanesque cathedrals, but I had never seen a cathedral that is such an incredible testament to both styles and such an amazing transition between the two. It's under major restoration and there is an archeological dig taking place just before the transept. When I arrived I was really scared that I wouldn't be let in. There were signs saying that it was completely closed. I guess they relaxed that a little, the choir was closed but the nave and the transept for the most part were open and I was able to walk around and see what I wanted to see.
