A leafy rectangular square in the middle of the medieval Écusson, named for the socialist politician assassinated on the eve of the First World War. Half a dozen cafés and brasseries take up most of the ground floor of the surrounding buildings, and the terraces are full from morning to past midnight in the warmer months.
It's the obvious place to come for an apéritif. Under the square is the crypt of the demolished medieval church of Notre-Dame-des-Tables — occasionally open for visits, with a small museum about the early history of Montpellier and the cult of the Black Virgin that drew medieval pilgrims here.
