I found something cool:
Medieval Fantasy City Generator
https://watabou.itch.io/medieval-fantasy-city-generator
>This application generates a random medieval city layout of a requested size. The generation method is rather arbitrary, the goal is to produce a nice looking map, not an accurate model of a city.
Protip: press "tab" for control window.
