After a tentative creation of several smaller suburban cemeteries, the Prefect Nicholas Frochot under Napoleon Bonaparte provided a more definitive solution in the creation of three massive Parisian cemeteries outside the city limits. Open from 1804, these were the cemeteries of Père Lachaise, Montmartre, Montparnasse, and later Passy; these cemeteries became inner-city once again when Paris annexed all neighbouring communes to the inside of its much larger ring of suburban fortifications in 1860. New suburban cemeteries were created in the early 20th century: The largest of these are the Cimetière parisien de Saint-Ouen, the Cimetière parisien de Pantin (also known as Cimetière parisien de Pantin-Bobigny, the Cimetière parisien d'Ivry, and the Cimetière parisien de Bagneux).[citation needed] Some of the most famous people in the world are buried in Parisian cemeteries.
