Bonn

We went to the botanical garden in Bonn. There were some cool plants I'd never seen before, like these lily pads (victoria amazonica).

Some other favorite plants. 

We also went to drachenfels. There's a castle on a hill that was finished in 1884. Stephan Sarter, a successful tycoon, funded the project as a personal escape.

There's no photography allowed inside, but there's a lot of beautiful stained glass, paintings, and dedications to great people. It only took 2 years to build the whole place.

The town hall in Bonn. It was built in the 1730s and is in the Rococo style.
