In 1817, the supposed remains of La Fontaine and Molière were transferred to Père-Lachaise (25th division), as were those of Héloïse and Abélard. Thereafter, demand rose sharply, and there were 33,000 tombs by 1830. Between 1824 and 1850, the cemetery was extended six times, bringing it to its current surface area of 44 hectares. The total number of tombs now stands at 70,000.
