The city of Paris (which is a departement in it's own right) owns the source of the river Seine. It
was bought in the 19th century. I wonder whether it's only a question of property, or that this tiny
spot is actually a part of the departement Ville de Paris (used to be called 'Seine', which explains
the departemental number 75, alphabetically wedged in between Savoie (Haute) and Seine-Maritime). In
that case, it is yet another departemental enclave in France (apart from the five Arif mentions on
his web site). If not, it is still a nice oddity. Does it ressort under the Parisian public gardens
service? A long trip for mowing the lawn.
