1. Nidaros Cathedral, Norway
In the Middle Ages, the Nidaros Cathedral was as important for pilgrims as Santiago de Compostela. Although the interior was stripped of many of its art treasures during the Reformation, it still has a special place among Europe’s cathedrals – not the least because of its sheer size. In fact, it is by far the biggest cathedral in Europe to be located so far from Rome, which is to say, all the way in mysterious and awe-inspiring Scandinavia.
I don’t know if Torvehallerne is really “hidden” but it does rock! Cheers from Copenhagen!
