Going back again to my old packs, here is a new version of my old town pack, I hope you enjoy this new version.
I suggest using a program called "Tiled" for easier map making.
To setup, create a new map with Tile Size 136x136
Create a new Tileset based on a single image with Tile Size 136x136 and load the Tileset Image.
Once you are done with the map you can export it as a single image and import it to Roll20.
TIP: You can move the map half a square up/down once in Roll20 so tokens would stand in the middle of the tiles (the ready to use buildings have been moved with this in mind so you can see how that looks)
If you have any question or problem about how to setup it, let me know and I will try to help you.
