The Communards’ Wall at the Père Lachaise cemetery is where, on May 28, 1871, one-hundred and forty-seven fédérés, combatants of the Paris Commune, were shot and thrown in an open trench at the foot of the wall.
To the French left, especially socialists and communists, the wall became the symbol of the people's struggle for their liberty and ideals. Many leaders of the French Communist Party, especially those involved in the French Resistance, are buried nearby.
The Père Lachaise cemetery was established in May 1804 on a land owned by the Jesuits for centuries, and where Père Lachaise, confessor of Louis XIV, lived the latter part of his life. Cemetery of the aristocracy in the 19th century, it also received the remains of famous people from previous eras.
