In the middle of the castle complex is a rather large cathedral.
The facade was decorated with glittering mosaics.
As well as beautiful masonary and metal work.
Goes to show that the Bohemian royalty back in the day (around 16th and 17th Centuries) were a pretty wealthy lot. These days, the Czech people have largely found their feet after the Communist era, but travelling from Germany into the Czech Republic, one can see that things aren’t so well-kempt. The Czechs still have some ways to go until the reach the affluence of their old western cousins.
In the end, there were simply too many people around the castle, and after a speedy walk-through, we ventured back down the hill to the elegant squares.
I heard from other travellers that Prague is often like this, and actually gets worse during the summer. Perhaps next time I should go in winter when the crowds are away?
