According to Wikipedia, The Cimetière des Chiens is believed to be the first zoological necropolis in the world. It opened in 1899 at 4 pont de Clichy on Île des Ravageurs in Asnières-sur-Seine, Île-de-France, France. Literally translated as the 'Cemetery of Dog', this elaborate pet cemetery is the burial site for many dogs but also for a wide variety of pets ranging from horses to monkeys to lions and even fish. Located in a northwest suburb of Paris, the pet cemetery caters to a very elite clientele. Filled with grand and ornate sculptures, at the entry is the monument to Barry, a Saint Bernard mountain rescue dog who died in 1814. The plaque says that during his lifetime, "Barry" was responsible for saving the lives of 40 people lost or trapped in the mountain snow.
Some of the cemetery's residents are famous in their own right such as Rin Tin Tin, the star of a number of Hollywood films, while others are the beloved pets of the wealthy who could afford this elaborate burial place such as film director Sacha Guitry. Buried here too, is the pet lion of stage actress, feminist, and co-founder of the cemetery, Marguerite Durand and the pet of Camille Saint-Saëns, composer of Carnival of the Animals.
The cemetery today is operated by the city of Asnières and in 1987, the government of France classified the cemetery as a historical monument. However, the cemetery has fallen on hard times and no longer draws very many tourists. Its owners have stated that they may have to close it.
Barbara Gordon produced a short film on this cemetery. It is very moving.
