What is it? A Roman Catholic basilica where you could hear a pin drop.
Why go? Of course, when checking out any new European city, you’ve simply got to pop into a few churches. But the Basilica of the Holy Blood is less of a shall-we-pop-in-there and more of a we-have-to-go-there kind of place. It’s famous because it’s home to a phial which is said to carry a cloth soaked in Jesus Christ’s blood, and the building itself is rather magical.
