Below is a short snippet of text that has been sitting around on my phone for a while, it kind of popped up into my head one day. It could very well be a piece of world building from a larger story, something like a fantasy novel with a steampunk setting. So far this novel remains unwritten, the only thing that exists is this short snippet:

Stockelheim is an ancient city, so old in fact that most of the city center is built on top of older buildings. It has a castle of course, every proper city needs a good castle.
