I made this a long time ago and has been used as our spawn on a couple of occasions. It has the potential to be used as a self contained town due to the fact i laid out plots to be given/sold to players to build starter homes within the walls. We have also used the plots as player shops.
There is also a small plot of land that can be used for whatever you want. We have used it for player markets and a pretty garden in the past.
If you have the craftbook plugin you can open and close the inner and outer gates :)
It has the main building in the middle which we have used as the mayors home and spawn in point with info walls and server shop.
The players have access to the tops and insides of the walls as well as the inside of the maingate and watchtowers.
Warning: This is a large Schematic so has the potential to crash the server when pasted so i recommend doing it when the server is empty or quiet.
