Mid XIXth, Sir Crèvecoeur gives to City a field to perpetuate a public space for fairs and markets. Decades later, the square is growing and connecting surroundings with streets. Today, three types of buildings are holding the place : Palace of Justice (public), Labour Market (union) and St-Peter church (religious). (translated source : calais.fr)

Intervention of Yves Lepere (Sevy office) is very humble and clear to unite this place with simple patterns, integrating very smoothly street parking.
