Sword of Spirit
Legend
My groups tend to be heavy on the in-character acting, and unless we knew it was a gargoyle infested area, I don't think a lot of our characters would feel comfortable routinely destroying art "just to be on the safe side." We'd probably be more likely to test out one statue by taking a swing at it and seeing if it fights back. If not, just keep a watchful eye on statues in case something is hidden amongst them.
Undead and cemetaries are harder. How often do graveyards that the PCs have any contact with or hear about *not* have undead? Makes you wonder why anyone buries their dead in the first place. Same basic solution though--have PCs interact with graveyards that are completely benign.
