City officials in Paris said they purchased four black sheep to serve as lawn mowers and chew away at the grass in a patch of land near the city's archives.
The archivists had initially asked for a donkey to chew down the grass in the patch of land, but the sheep were deemed more appropriate, The New York Times reported.
Rene Dutrey, the adjunct mayor for environmental and sustainable development said the sheep cost the city $335.
"This is really not a one-shot deal," he said, explaining the sheep would remain in the patch of land until October.
Residents, though, have been encouraged to come visit the animals and take a look at the city's archives while they're at it.
