Between 1,000 and 3,000 anarchists are expected to descend on the northwest municipality of St-Imier, normally home to 4,800 people, for the International Anarchism Gathering from August 8 to 12.
"We wanted to meet up with anarchists of all persuasions and from different countries," said Michel Nemitz of the St-Imier anarchist and libertarian
cooperative Espace Noir, quoted by the Swiss ATS news agency.
Participants will take part in talks, debates, shows and generally keep the anarchy flame alive.
The meeting comes 140 years after the umbrella group Anarchist International was formed in St-Imier following clashes between anarchist and
Marxist members of the International Workingmen's Association at the Hague Congress.
