I found some great terrain pieces for my D&D minis at a local Dollar Tree. I picked up four cemetery gates, 4 mausoleums, and a pack that had three gargoyles for only nine bucks! While I can't tell you the exact scale they look great next to minis (as you can see below). You can order a mixed bundle of them here.
