I was posting yesterday, regarding Tamworth Castle, which I found on the interwebs. The maps of that castle are on the above-linked website, and I found them suitable enough for my purposes that I copied them onto graph paper.
Here is the second floor of that Castle. As I mentioned previously, I like that there are several sets of stairs, leading to different areas of that castle: those stairs give players more choices as to where they want to explore. In addition, it allows me to populate the castle with several different monsters, all of whom have their own access to their lairs, without conflicting with the other denizens of the castle.
I will post the third floor tomorrow, as I am busy preparing for gaming night tonight.
