A gargoyle was a Cardassian decorative object, carved in the shape of a Cardassian person and/or animal, often found on bedposts.
In 2369, while visiting Deep Space 9, the Arbazan ambassador Taxco expressed her distaste at having to sleep another night on a Cardassian bed "with those gargoyles staring from the woodpoles." (DS9: "The Forsaken")
An Akaali "gargoyle"
Statues seen in the curio shop of Garos on the Akaali homeworld in the Star Trek: Enterprise first season episode "Civilization" bear a striking resemblance to gargoyles. Three of them were later sold off on the It's A Wrap! sale and auction on eBay. [1]
