Visiting for the first time in January 2015, and then again in August, I was pleased to see the High Gothic enormity of the Cathedral with my own eyes.

It survived repeated Allied aerial bombardments of the city in the Second World War, including the RAF’s first ‘thousand bomber raid’, making it the German counterpart of St Paul’s in London, which miraculously escaped the Blitz.

I enjoyed looking at the Shrine of the Three Kings, whereas the Crucifix of Archbishop Gero has less of a 'wow factor', despite being just as significant (possibly more).

The façade of the cathedral is the largest of any church in the world, and intricately detailed. It is inscribed as a WHS because it is a testament to the ‘enduring strength of European Christianity”. This is demonstrated by the fact that over its six century gestation period, generations of builders stayed true to its original design.
