Built in the 18th century by the prince-electors of Köln, this grand palace now houses Bonn's university. If the weather is good, stroll through Hofgarten park in front of it. When Bonn was a capital, this patch of grass drew tens of thousands to antinuclear demonstrations. Today it's mostly used for games of pickup soccer and ultimate Frisbee.
