I recall I walked pretty much everywhere in Georgetown. Heading north from the ferry terminal I turned the corner to find myself at Fort Cornwallis. Now, there are keep out signs and keep out signs. This is one of the most unambiguous I've ever seen. What I like about it is the multicultural aspect. The center graphic speaks for itself, emphasized by the command in four languages, one in each corner. I don't actually remember where this was but I think it was somewhere in the vicinity of Fort Cornwallis protecting the north-east corner of Penang Island and Georgetown behind it.
