According to the signs the festival was called the "Gaukler & Kleinkunstfestival". (German speaking people love long words!) I had to translate that on Google Translate when I got back to my computer. It means "Juggler and Cabaret Festival".
There were several stages set up throughout the "Old Town", and a variety of entertainers were performing. The first stage that I came to was set up in front of the "Rathaus", the City Hall.
The act that was in progress was called, if I remember correctly, "Bubble Circus". The two performers were from Italy and Argentina. The lighting was not very good, but these photos and videos should give you an idea of the amazing things that they did with bubbles...
Later I saw some more acts as the evening progressed. There were a couple of mimes who were very boring. The jugglers in the video below were also tedious, until they really got down to juggling.
The streets were lined with food stands selling everything from Indian curry to cotton candy.
The "Flammkuchen" that I ordered was good, but not as good as what Brigitta and I had made.
As I walked back to the hotel, there was a view of Lenzburg Castle illuminated on the hill above the city.
