The history of the City of Paris began in 1357, when Etienne Marcel, provost of the merchants (holder of a function that currently amount to a mayor), purchased a building that was in that place to gather policy makers, representatives of the Parisian bourgeoisie.
Today, this neo-Renaissance building is a reconstruction of the nineteenth century, but is still home to the municipality of the city. Presides over a large pedestrian square where different seasonal activities (skating, relay games ...).
In any case, it is hard to imagine that in an era when it was called the Place des Grèves, ran there on death row. The city only reveals a luxurious interior to the public during tours.
