It was under Napoleon, in 1804, that lost objects began to be centralized at the headquarters of the Police Prefecture, and not long after that the Bureau of Found Objects was officially formed.
"On the southern edge of Paris, a five-thousand-square-foot basement houses the city’s lost possessions. The Bureau of Found Objects, as it is officially called, is more than two hundred years old, and one of the largest centralized lost and founds in Europe. Any item left behind on the Métro, in a museum, in an airport, or found on the street and dropped, unaddressed, into a mailbox makes its way here, around six or seven hundred items each day. Umbrellas, wallets, purses, and mittens line the shelves, along with less quotidian possessions: a wedding dress with matching shoes, a prosthetic leg, an urn filled with human remains. The bureau is an administrative department, run by the Police Prefecture and staffed by very French functionaries—and yet it’s also an improbable, poetic space where the entrenched French bureaucracy and the societal ideals of the country collide. ... It is with a similar hint of romance that many French people d’un certain âge embrace this mythical public service, though those in the younger generation, armed with smartphones and having never heard the song, often do not know of its existence. ..."
