Just a plain template for the west gates of a reasonably big city. Left uncluttered to modify to your heart's content!

EDIT: So I added a few more textures to make it less bland. The problem with city gates on flat lands is that the field leading to the gate should be clear of cover for any approaching enemies. There probably shouldn't be any trees... but let's just say that the gates are rarely attacked. Plus, they're easy to get rid of. Hopefully the new brushes are an improvement!
