Castles of Augustusburg and Falkenlust by Els Slots
Brühl is a little town near Cologne that is famous for its amusement park 'Phantasialand'. I drove 2,5 hours from my home to see the castles though.
After I arrived I first did a guided tour of the Augustusburg Castle. There I learned about the mighty Clemens August, who ruled a large part of northwestern Germany in the 18th century. One of his hobbies, besides hunting, was building castles. It cost him so much money that after his death all the furniture had to be sold to pay the debts. But the fine rococo palaces are still standing. In Augustusburg you really should see the staircase, by which Clemens August meant to impress the humble visitors that came to see him.
The other castle that is part of this world heritage site, Falkenlust, is being restored at the moment. It's a lot smaller but in nice quiet surroundings. The small chapel in the woods to the right is also very pretty.
