Hello, PumpkinPieFTW and i build this old factory. When they used it in old times, they used this as a mine. That is the reason there are minecarts going down into the ground. Nowadays they use it as a butcher. Wich is quite usefull for work. On our server you can even be a butcher yourself by joining the job ( if you want join our server negotium.mcjoin.it you can see the building)
