Maps are usually available at the conservation office of most of the larger cemeteries in Paris. These are not typically the best guides, particularly for a cemetery as large as Père-Lachaise.
In fact, there are "non-official" maps available for purchase at vendors just outside the entrances to Père-Lachaise. The best map is probably the Editions Métropolitain map, which is often for sale at the entrance just across from the Père-Lachaise Metro stop.
With the exception of the three official guide maps in pdf format, which will download the map directly to your computer, the following maps open in a separate window; simply right-click or control-click on the image:
- Montmartre (374K PDF)
- Montparnasse (302K PDF)
- Père-Lachaise (595K PDF)
Pere-Lachaise.com has a wonderful interactive map feature.
