This is a really special WHS - for so many reasons.
I love that it is tiny but still has so much to see inside. There are different parts to the cathedral and so much detail in each of them.
I love that it is easily accessible from a few different countries, meaning that you will naturally path through Aachen and be able to see it if you are travelling between countries in this part of Europe.
I love the history and the reason for it being constructed, plus its use for the many centuries afterwards.
And I love that this was the first site named in Germany. It's so fitting because you can learn so much about German history from this one small building - so much can be traced back to here somehow.
This is one of those must visit sites and so it's luck that it's so easy to do so.
