I notice via the Swiss Webcams that a Circus has set up in the Market Square in Vevey. This is apparently the same one that was in Montreux last summer.

Is this a Swiss Circus? Does it travel around widely? What sort of acts do the circus have there? Do they still have performing animals for instance?

Does the Saturday market move elsewhere in Vevey while the Circus is on or do they cancel it?

It's Cirque Nock (website in the three national languages).

Their last plays in Vevey are today (15:00, 20:15) and tomorrow (14:30, 18:00). They move around pretty quickly when on tour, except for a few bigger cities.

The program and some photos are on their website.

The normal saturday morning market is still held but it’s at the far end of the square, by the lake. The big Vevey folklorique market does not start until July.
There is also another Swiss circus called Knie. If the two amalgamated we would then, presumably, have the Nock Knie Circus !

Thanks for the link! I have not seen the Cirque Knie since I was a teenager, I may go to Luzern or Bern one day just to see them!
