Ancona is the part of the world map where all players start and stay till they are level 9, at which point they have to relocate their city to Rome in order to grow further.
It's also the place where your menu is slowly expanded with various new tabs.
Place in the world mapEdit
Altough not directly visible to you from the start, Ancona is placed in the very centre of what we now call Italy. It is a great place to start and get to learn how to play the game. This wiki is also helpfull with that.
